利用JUROGAM γ谱仪、RITU充气反冲分离器和GREAT示踪谱仪，对轻铂同位素Pt 169 -173的Yrast态进行了反冲衰变示踪实验研究。首次在奇氮同位素Pt-169和Pt-173中建立了γ射线跃迁，并扩展了Pt-170和Pt-172中的γ射线跃迁序列。我们讨论了Pt-170、Pt-172和Pt-173的弱形变yrast结构被自旋类似于8h的形变入侵组态穿过的可能性。
The yrast states in the light platinum isotopes Pt169-173 have been investigated in a recoil-decay tagging experiment using the JUROGAM gamma-ray spectrometer in conjunction with the RITU gas-filled recoil separator and the GREAT tagging spectrometer. Gamma-ray transitions have been established for the first time in the odd-N isotopes, Pt-169 and Pt-173, and the yrast sequences in Pt-170 and Pt-172 have been extended. We discuss the possibility that the weakly deformed yrast structures of Pt-170, Pt-172, and Pt-173 are crossed by a deformed intruder configuration at spin similar to 8h.
