在高分辨率（He,）电荷交换实验中研究了双（）衰变核体和te的Gamow-Teller （GT）强度分布。实验在大阪核物理研究中心进行，实验采用了420兆电子伏特入射光束和大雷电磁谱仪。最终状态能量分辨率达到35kev。在两个碲核的衰变矩阵元素的背景下，给出并讨论了最终核在低激发能下提取的GT强度分布。te中额外的中子对似乎使低能GT分布的碎片化程度有所增加。
Gamow-Teller (GT) strength distributions have been investigated in a high-resolution (He,) charge-exchange experiment on the double-() decaying nucleiTe andTe. The experiment was carried out at the Research Center for Nuclear Physics, Osaka, with a 420-MeV incidentHe beam and the Grand Raiden magnetic spectrometer. A final-state energy resolution of 35 keV was achieved. The extracted GT strength distributions at low excitation energies in the final nucleiI andI are presented and discussed in the context of thedecay matrix elements for the two tellurium nuclei. The additional neutron pair inTe seems to produce a moderate increase in the fragmentation of the low-energy GT distribution.
