项目摘要

The lifetime of a nuclear state is related to the initial and nal wavefunctions thatdefine the states by the quantum mechanical Fermi's golden rule. When a nucleusundergoes de-excitation, it typically does so through the emission of a gammaray.This project aims to obtain lifetime measurements for nuclear states through de-tection of these emitted gamma rays, particularly for proton rich nuclei. Thelifetime measurements will be made using plunger and/or fast timing techniques,both of which are active areas of research within the nuclear department.These lifetime measurements will be made with the intention of inferring someinformation regarding the structure of the nuclei concerned. This is as proton richnuclei provide a method of probing weak but important aspects of the nuclearforce generally masked in regions closer to stability. One such example being thedirect measurement of effective charges of nucleons which are used to calculatetransition matrix elements in theory.

核状态的寿命与量子力学费米黄金法则定义状态的初始波函数和最终波函数有关。当核经历去激发时，它通常是通过发射伽玛射线来实现的。该项目旨在通过探测这些发射的伽马射线，特别是富含质子的原子核，获得核国家的寿命测量。寿命测量将使用柱塞和/或快速定时技术进行，这两种技术都是核部门的活跃研究领域。这些寿命测量的目的是推断有关原子核结构的一些信息。这是因为富含质子的核提供了一种探测核力的微弱但重要方面的方法，核力通常被掩盖在更接近稳定的区域。一个这样的例子是直接测量核子的有效电荷，它在理论上被用来计算跃迁矩阵元素。
