核物理中的Majorana和准stationary states
Majorana and the quasi-stationary states in Nuclear Physics
摘要：
本文详细讨论了Majorana早在1930年提出的一个描述α粒子轰击原子核人工衰变的完整理论模型，并给出了该模型的基本实验依据。马约拉纳（在其他预测中）得到了核过程积分截面的显式表达式，这是实验中感兴趣的直接可测量量。虽然这是第一次应用的概念准定态的核物理问题，似乎也未发表马约拉纳的工作预期了几年的相关开创性文件法诺对原子物理学。
英文摘要：
A complete theoretical model describing artificial disintegration of nuclei by bombardment with alpha-particles, developed by Majorana as early as in 1930, is discussed in detail alongside the basic experimental evidences that motivated it. By following the quantum dynamics of a state resulting from the superposition of a discrete state with a continuum one, whose interaction is described by a given potential term, Majorana obtained (among the other predictions) the explicit expression for the integrated cross section of the nuclear process, which is the direct measurable quantity of interest in the experiments. Though this is the first application of the concept of quasi-stationary states to a Nuclear Physics problem, it seems also that the unpublished Majorana's work anticipates by several years the related seminal paper by Fano on Atomic Physics.
