Abstract

This work features preliminary results from a recent experimental campaign at IFIN-HH, Romania, aimed at measuring lifetimes of excited states in the neutron-rich 180Hf, by means of the RDDS technique. The 181Ta(11B,12C)180Hf proton pick-up reaction was used to populate excited states in the 180Hf nucleus. The ROSPHERE array loaded with 25 HPGe detectors was employed for the detection of the γ transitions depopulating the levels of interest. The array was coupled to the SORCERER particle detector and a plunger device enabling the study of p-γ and p-γ-γ coinciding events. Six different plunger foil distances were chosen, allowing for the construction of the decay curves of the observed γ transitions of interest, from which the corresponding level lifetimes can subsequently be deduced.

180Hf核结构的实验研究:初步结果

这项工作的特点是最近在罗马尼亚IFIN-HH进行的一项实验的初步结果，该实验旨在通过RDDS技术测量富中子180Hf激发态的寿命。利用181Ta(11B,12C)180Hf质子吸收反应填充180Hf核的激发态。装有25个HPGe探测器的ROSPHERE阵列被用于检测减少感兴趣水平的γ跃迁。该阵列与SORCERER粒子探测器和柱塞装置耦合，可以研究p-γ和p-γ-γ重合事件。选择了六种不同的柱塞箔距离，允许构建观测到的感兴趣的γ跃迁的衰减曲线，由此可以推导出相应的能级寿命。
