标题： Evaporation of alpha particles from $^31$P nucleus

摘要： α粒子的能量谱已与蒸发残留物同时测量，用于研究化合物核$^31$P 的衰变，该化合物核是在反应$^19$F (96 MeV) +$^12$C 中产生的。数据已与统计模型代码 CASCADE 的预测进行了比较。 观察到为了解释蒸发的α粒子能量谱的形状，需要考虑化合物核中的显著形变效应。 显示英文摘要

摘要： The energy spectra of alpha particles have been measured in coincidence with the evaporation residues for the decay of the compound nucleus $^31$P produced in the reaction $^19$F (96 MeV) + $^12$C. The data have been compared with the predictions of the statistical model code CASCADE. It has been observed that significant deformation effect in the compound nucleus need to be considered in order to explain the shape of the evaporated alpha particle energy spectra.
