Das Verständnis des Aufbaus der Atome und der Atomkerne ist entscheidend, um die Welt verstehen. Mit einem besseren Verständnis der Kräfte in den Kernen und wie sie aufeinander wirken, können Forscher neue Technologien entwickeln, die uns helfen, unser Leben zu verbessern. Es kann uns beispielsweise ermöglichen, energiereichere Energiequellen als heutige fossil betriebene Kraftwerke herzustellen oder effizientere Wege finden, unsere Ressourcen im Alltag besser nutzen. Rutherford war einer der Ersten, der die Grundlagen der Kernphysik erforschte und dazu beitrug, das Verständnis für den Aufbau der Atome zu stärken.

Nuclear structure Physics connects to some of our fundamental questions about the creation of universe and its basic constituents. At the same time, precise knowledge on the subject has lead to develop many important tools of human kind such as proton therapy, radioactive dating etc. This book contains chapters on some of the crucial and trending research topics in nuclear structure, including the nuclei lying on the extremes of spin, isospin and mass. A better theoretical understanding of these topics is important beyond the confines of the nuclear structure community. Additionally, the book will showcase the applicability and success of the different nuclear effective interaction parameters near the drip line, where hints for level reordering have already been seen, and where one can test the isospin-dependence of the interaction. The book offers comprehensive coverage of the most essential topics, including: ¿ Nuclear Structure of Nuclei at or Near Drip-Lines ¿ Synthesis challenges and properties of Superheavy nuclei ¿ Nuclear Structure and Nuclear models - Ab-initio calculations, cluster models, Shell-model/DSM, RMF, Skyrme ¿ Shell Closure, Magicity and other novel features of nuclei at extremes ¿ Structure of Toroidal, Bubble Nuclei, halo and other exotic nuclei These topics are not only very interesting from theoretical nuclear physics perspective but are also quite complimentary for ongoing nuclear physics experimental program worldwide. It is hoped that the book chapters written by experienced and well known researchers/experts will be helpful for the master students, graduate students and researchers and serve as a standard & uptodate research reference book on the topics covered.

The monograph discusses the physical foundations of a new method of doping semiconductors, the basic element of which is nuclear reactions that occur in the volume of a semiconductor under the influence of fast charged particles, neutrons, high-energy gamma radiation, as well as the inevitably occurring side effects - the formation of radiation defects, the kinetics of their accumulation and annealing. Detailed data are presented on the technology of uniform irradiation of bulk ingots with neutrons depending on the specific design of the nuclear reactor, the medium and modes of annealing of radiation defects, the requirements for the starting material, and the electrophysical properties of doped silicon crystals are considered. The sources of radioactive contamination of the ingots during the irradiation process and the technological methods of their deactivation to a safe level are analyzed.The monograph is designed for scientists and production personnel interested in the problems of solid state radiation physics and radiation materials science of semiconductors and devices based on them, as well as graduate students and students of relevant specialties.

Tucked up against the Rocky Mountains, just west of Denver, sits the remnants of one of the most notorious nuclear weapons sites in North America: Rocky Flats. With a history of environmental catastrophes, political neglect, and community-wide health crises, this site represents both one of the darkest and most controversial chapters in our nation's history, and also a conundrum on repurposing lands once considered lost. As the crush of encroaching residential areas close in on this site and the generation of Rocky Flats workers passes on, the memory of Rocky Flats is receding from the public mind; yet the need to responsibly manage the site, and understand the consequences of forty years of plutonium production and contamination, must be a part of every decision for the land's future.

A radical reinterpretation of the physics that governs out universe. This follow-up to "A Unification Theory of the Universe," examines what happens if we use a point that has volume as foundation, rather than the Euclidean basis of a point "that has no part," meaning it has only two dimensions.

Recent advancements in generation of intense X-ray laser ultrashort pulses open opportunities for particle acceleration in solid-state plasmas. Wakefield acceleration in crystals or carbon nanotubes shows promise of unmatched ultra-high accelerating gradients and possibility to shape the future of high energy physics colliders. This book summarizes the discussions of the "Workshop on Beam Acceleration in Crystals and Nanostructures" (Fermilab, June 24–25 , 2019), presents next steps in theory and modeling and outlines major physics and technology challenges toward proof-of-principle demonstration experiments.

En el presente trabajo se analizó la influencia de diferentes parámetros referentes al suministro de dióxido de carbono (CO2) en cultivos de una cepa colombiana de la especie de microalga Botryococcus braunii. Para ello se plantearon diseños experimentales factoriales (Central Compuesto 22), con el fin de analizar la influencia estadística de parámetros técnicos (geometría del reactor y tipo de difusor), parámetros de proceso (concentración de CO2) y parámetros de suministro (continuo o por pulsos) sobre la dilución de CO2 en el cultivo y la producción de Biomasa, Lípidos e Hidrocarburos para esta especie de microalga. Se encontró que la altura del fotobiorreactor y el tipo de difusor tuvieron una influencia significativa sobre la dilución de CO2 en el medio de cultivo; a mayores alturas (>35 cm) y pequeños tamaños de burbuja se obtuvieron diluciones más altas. También se encontró que el cambio en los niveles de concentración de CO2 tuvo una influencia significativa sobre la producción de biomasa, lípidos e hidrocarburos.

This book is based upon a part of the invited and contributing talks at the 25th International Symposium on Ion-Atom Collisions, ISIAC (biennial), held on July 23–25, 2017 in Palm Cove, Queensland, Australia. To aid the general reader, all the authors tried to present their chapters in the context of the development of the addressed particular themes and the underlying major ideas and intricacies. Some chapters contain new results that have not been previously published elsewhere. Whenever possible, the authors made their attempts to connect the basic research in atomic and molecular collision physics with some important applications in other branches of physics as well as across the physics borders. It is hoped that the material presented in this book will be interesting and useful to the beginners and specialists alike. The contents and expositions are deemed to be helpful to the beginners in assessing the potential overlap of some of the presented material with their own research themes and this might provide motivations for possible further upgrades. Likewise, specialists could take advantage of these reviews to see where the addressed themes were and where they are going, in order to acknowledge the fruits of the efforts made thus far and actively contribute to tailoring the directions of future research. Overall, this book is truly interdisciplinary. It judiciously combines experiments and theories within particle collision physics on atomic and molecular levels. It presents state-of-the-art fundamental research in this field. It addresses the possibilities for significant and versatile applications outside standard atomic and molecular collision physics ranging from astrophysics, surface as well as cluster physics/chemistry, hadron therapy in medicine and to the chemical industry. It is then, as Volume 2, fully in the spirit of the "Aims and Scope" of this book series by reference to its "Mission Statement".
