Topic（题目）：Alpha Decay – a collective feature of the atomic nucleus?
Speaker（报告人）：Prof. Ramon Wyss (KTH the Royal Institute of Technology)
The probabilistic interpretation of quantum mechanics celebrated its first large triumph through the introduction of barrier penetration in alpha decay, as shown by Gamow. Early data had already revealed the exponential dependence on the decay energy available by means of the Geiger Nuttall law. One can state that alpha decay has been of tremendous importance for the development of quantum mechanics and nuclear physics. In this talk, I will review some of the early findings with respect to alpha decay and discuss how it can reveal many aspects of nuclear structure, last not least shape coexistence. Microscopic calculations of alpha decay has always been a challenging task. I will review the formalism and address the question, to what extent alpha decay constitutes a collective phenomenon of the nucleus.
