accurate measurement of strength function of deeply bound hole states and search for the chaotic component

在中等质量原子核上进行（p, d）反应实验，测量了在激发能0 ~ 8 MeV范围内遗漏氘核的光谱。实验采用来自九州大学和建波大学的串联加速器的20 MeV极化质子束，九州大学实验采用SSD望远镜获得中分辨率数据，研究了连续谱中的泊松分量和混沌分量。在筑波大学的实验中，用ESP-90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原子核的激发能为45 MeV左右。

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.
