Pb同位素的巨单极共振

The Giant Monopole Resonance in Pb isotopes

Elias Khan

摘要:

本文分析了从等振幅巨磁共振(GMR)测量中提取核不可压缩性的方法。配对效应和磁增强效应(MEM)都对双闭壳层$^{208}$ Pb核与其它Pb同位素之间的巨磁电阻能移起作用。配对效应是在显微镜下预测的,而MEM效应是在现象学上评价的。需要对开壳层铅同位素的巨磁电阻进行准确测量。

英文摘要:

The extraction of the nuclear incompressibility from the isoscalar giant monopole resonance (GMR) measurements is analysed. Both pairing and mutually enhanced magicity (MEM) effects play a role in the shift of the GMR energy between the doubly closed shell $^{208}$Pb nucleus and other Pb isotopes. Pairing effects are microscopically predicted whereas the MEM effect is phenomenologically evaluated. Accurate measurements of the GMR in open-shell Pb isotopes are called for.
