摘要

由于α粒子束与氚的相互作用，使用三个粒子3H（α，tt）p、3H（a，t3He）n和3H（β，td）d反应（Eα=67.2 MeV）的粒子衰变光谱获得了tt、t3He和dd的二维重合光谱。用蒙特卡罗方法获得了7个4He激发态的激发能和能宽，以及它们不同衰变模式（即t+p、n+3He和d+d）的比值。

On the Peculiarities of Studying Unbound Excited States of 4He Nucleus by α + 3H Interaction

Due to the alpha-particle beam interaction with tritium, the two-dimensional spectra of tt, t3He, and dd coincidences are obtained using the particle-decay spectroscopy from three-particle 3H(α,tt)p, 3H(α,t 3He)n, and 3H(α,td)d reactions (Eα = 67.2 MeV). Excitation energies and energy widths for seven excited 4He states, as well as the ratio of their different decay modes, namely t + p, n + 3He, and d + d, are obtained by using the Monte Carlo method.
