Abstract: It is shown, that the Gamow-like model with only one adjustable parameter–radius constant—is able to reproduce well the alpha-decay half-lives for all even–even nuclei with the proton number larger than 50. The systematics for odd–A and odd–odd isotopes can be also well described when one introduces an additional hindrance factor. A similar model based on the W J Świa̧tecki idea from 1955 is developed to reproduce the spontaneous fission half-lives of transactinide nuclei. The achieved accuracy of reproduction of the data is better than that obtained in more advanced theories.

This book has three volume. The first volume is mainly devoted to the macroscopic-microscopic theory in its traditional form and extended to very high mass and charge asymmetry. Applications of this theory to the emission of different kinds of charged particles from nuclei are presented in the second volume, where recent experimental achievements in alpha decay, proton, and heavy ion (14C, 24Ne, 28Mg, etc.) radioactivities are also discussed. Experiments on spontaneous fission, fission isomers, and more complex phenomena like particle-accompanied fission,delayed processes: p, a, 2p, t, n, 2n, 3n, and the new mechanism of cold fission (or fission with compact shapes) are described in detail in the third volume.

Nowadays experimental nuclear physics pushes its limits towards highly unstable nuclei. The theoretical description of proton-rich and neutronrich nuclei or superheavy elements has become an important part of the modern nuclear physics. The main tool to investigate such unstable nuclei concerns radioactive decays, from proton emission to fission processes. We review the main theoretical methods describing decay processes induced by the strong interaction, like Coupled channels method for Gamow resonances, R-matrix theory, Distorted wave approach, Semiclassical approach, Multi step and Two center shell model. Thus, most of the book is addressed to a broad audience within the nuclear physics community. Secondly, this book is an attempt to clarify some fundamental aspects connected with the fine structure or anisotropy in alpha decay and ternary cold fission. Finally, the self consistent microscopic theory of the alpha decay is analyzed.

Discover the essential thinking tools you’ve been missing with The Great Mental Models series by Shane Parrish, New York Times bestselling author and the mind behind the acclaimed Farnam Street blog and “The Knowledge Project” podcast. This first book in the series is your guide to learning the crucial thinking tools nobody ever taught you. Time and time again, great thinkers such as Charlie Munger and Warren Buffett have credited their success to mental models–representations of how something works that can scale onto other fields. Mastering a small number of mental models enables you to rapidly grasp new information, identify patterns others miss, and avoid the common mistakes that hold people back. The Great Mental Models: Volume 1, General Thinking Concepts shows you how making a few tiny changes in the way you think can deliver big results. Drawing on examples from history, business, art, and science, this book details nine of the most versatile, all-purpose mental models you can use right away to improve your decision making and productivity. This book will teach you how to: Avoid blind spots when looking at problems. Find non-obvious solutions. Anticipate and achieve desired outcomes. Play to your strengths, avoid your weaknesses, … and more. The Great Mental Models series demystifies once elusive concepts and illuminates rich knowledge that traditional education overlooks. This series is the most comprehensive and accessible guide on using mental models to better understand our world, solve problems, and gain an advantage.

The first measurement of angular distribution of emitted protons was announced at this conference. In addition, the conference covered the recent developments in the field of exotic decays competing with ß+ decay in proton rich nuclei. Topics included: experiments on one proton emission, theory on one proton emission, two proton emission, alpha emission, beta delayed proton emission and gamma spectroscopy, nuclear astrophysics, and experimental techniques.

This handbook is a comprehensive, systematic source of modern nuclear physics. It aims to summarize experimental and theoretical discoveries and an understanding of unstable nuclei and their exotic structures, which were opened up by the development of radioactive ion (RI) beam in the late 1980s. The handbook comprises three major parts. In the first part, the experiments and measured facts are well organized and reviewed. The second part summarizes recognized theories to explain the experimental facts introduced in the first part. Reflecting recent synergistic progress involving both experiment and theory, the chapters both parts are mutually related. The last part focuses on cosmo-nuclear physics—one of the mainstream subjects in modern nuclear physics. Those comprehensive topics are presented concisely. Supported by introductory reviews, all chapters are designed to present their topics in a manner accessible to readers at the graduate level. The book therefore serves as a valuable source for beginners as well, helping them to learn modern nuclear physics.
