Experiments of (p, d) reactions on medium mass nuclei were performed to measure spectra of omitted deuterons in the excitation energy region, 0 - 8 MeV.The experiments were performed with 20 MeV polarized proton beam from a tandem accelerator of Kyushu University and Tsukuba University, In the Kyushu University experiments, a SSD telescope was used to obtain the data with medium resolution, and investigated the Poisson and chaotic components in the continuum spectrum. In the Tsukuba University experiments, measurements with high resolution were performed with spectrograph ESP-90. As a result, we found that the separation of Poisson and chaotic components took place at around the excitation energy of 4 5 MeV of nuclei.

在中等质量核上的(p，d)反应实验中，测量了激发能区0-8 MeV范围内被忽略的氚的能谱。实验用来自九州大学和筑波大学串列加速器的20 MeV极化质子束进行。在九州大学的实验中，用SSD望远镜获得了中等分辨率的数据，并研究了连续谱中的泊松和混沌成分。在筑波大学的实验中，用ESP-90型光谱仪进行了高分辨率的测量。结果发现，泊松分量和混沌分量的分离发生在4 5 MeV左右的激发能附近。
