【摘要】 在中国原子能科学研究院的HI-13串列加速器上通过157Gd(19F,5n)171Ta重离子熔合蒸发反应布居了171Ta的高自旋态,以多普勒移动衰减法的峰形分析法分析了171Ta h9/2质子1/2[541] 转动带的6条能级的寿命,得到了这6条能级的平均寿命值.
【Abstract】 The high spin states of 171Ta have been populated via heavy ion fusion evaporation reaction 157Gd (19F, 5n)171Ta at the HI-13 tandem accelerator in China Institute of Atomic Energy. The lifetimes of the high spin states in 171Ta have been measured by using the Doppler Shift Attenuation Method (DSAM). Six levels of its h9/2 proton 1/2[541] band have been analyzed and their lifetimes have been deduced from the experimental data.
【Key words】 high spin state; Doppler shift attenuation method; lifetime;
