摘要

我们介绍了一项专门测量 205Bi 的低洼激发态寿命的实验结果。我们在单质子转移反应 204Pb(16O,15N)205Bi中对该原子核进行了研究，并利用反冲距离多普勒频移法测定了\(11/2^-_1\)、\(7/2^-_1\)、\(5/2^-_1\)、\(7/2^-_2\)态的寿命。将结果与粒子-核心耦合模型的预期结果进行比较后发现，这些态的结构具有较低的四极集合性。

Experimental study of the quadrupole collectivity of the low-lying states of 205Bi

We present results from an experiment dedicated to measure the lifetimes of the low-lying excited states of ²⁰⁵Bi. This nucleus was studied in the one-proton transfer reaction ²⁰⁴Pb(¹⁶O,¹⁵N)²⁰⁵Bi and the lifetimes of the \(11/2^-_1\), \(7/2^-_1\), \(5/2^-_1\), \(7/2^-_2\) states were determined by utilizing the Recoil Distance Doppler Shift method. Upon comparing the results with the expectations of the particle-core coupling model, it indicates a low quadrupole collectivity in the structure of these states.
