偶偶核~(178)Pt到~(186)Pt的第2个0~+激发态能量非常低,只有约500keV。这表明这些核的第1个0~+态和第2个0~+态是拥有不同内禀形状的。为了深入研究这些Pt同位素的结构,需要进一步研究他们的E2跃迁概率B(E2)。实验上,通过直接测量能级寿命来得到B(E2)值。本工作采用反冲距离多普勒位移法~[1](RDDS)测量~(180)Pt低激发的寿命。实验在中国原 The energies of the second 0 ~ + excited states of even ~ ~ (178) Pt ~ (186) Pt are very low, only about 500 keV. This indicates that the first 0 ~ + state and the second 0 ~ + state of these nuclei have different intrinsic shapes. In order to further study the structure of these Pt isotopes, their E2 transition probability B (E2) needs to be further studied. Experimentally, B (E2) values ​​are obtained by directly measuring the energy level lifetime. In this work, the recoil distance Doppler shift method ~ [1] (RDDS) was used to measure the lifetime of low excitation of ~ (180) Pt. Experiment in China original
