Abstract

A survey of experimental results on the level structure in the heavy helium isotope \({}^{6}\)He that were obtained in reactions induced by stopped pion absorption in \({}^{9}\)Be, \({}^{10,11}\)B, and \({}^{12}\)C light nuclei is presented. The respective measurements were performed on the low-energy pion channel of the accelerator at the Los Alamos National Laboratory (LANL) by means of a two-arm semiconductor spectrometer. A high statistical significance of the results was attained over a broad excitation-energy range extending up to 40 MeV. Several highly excited states, including \(t+t\) cluster resonances, were revealed for the first time.

摘要

关于重氦同位素\（{} ^ {6} \） He中能级结构的实验结果的调查，这是由于\（{} ^ {9} \） Be，\（给出了{} ^ {10,11} \） B和\（{} ^ {12} \） C轻核。各自的测量是通过两臂半导体光谱仪在洛斯阿拉莫斯国家实验室（LANL）的加速器的低能离子通道上进行的。在高达40 MeV的宽激发能量范围内，获得了具有高度统计学意义的结果。首次揭示了几个高激发态，包括\（t + t \）团簇共振。
