(11)B（p，3α）是一种干净惯性压缩核聚变的新途径．为测量其核反应截面，应用核反应理论，对反应中伴随8Be第一激发态产生的α粒子的能谱进行理论拟合，通过拟合将其同8Be基态和第一激发态衰变产生的α粒子能谱分开．理论拟合同实验谱图符合得很好．
(11) B (p, 3α) is a new way of clean inertial compression fusion. In order to measure the cross section of nuclear reaction, the energy spectrum of the α particle with 8Be first excited state in the reaction was theoretically fitted by using the theory of nuclear reaction. By fitting the α particle energy that can be generated by decaying the same with the 8Be ground state and the first excited state Separate spectrum. The theoretical fit is in good agreement with the experimental spectrogram.
