Abstract

An approach to describing main properties of isoscalar giant multipole resonances in medium-heavy closed-shell nuclei is proposed within the particle–hole dispersive optical model formulated recently. The description includes the energy-averaged strength function, projected transition density, and partial branching ratios for direct single-nucleon decay. The results obtained within this approach for the \({}^{208}\)Pb nucleus are compared with available experimental data.

摘要

在最近建立的粒子-孔色散光学模型中，提出了一种描述中等重量的闭合壳核中等量超巨子共振主要性质的方法。该描述包括能量平均强度函数，预计的跃迁密度以及直接单核子衰变的部分分支比。用这种方法获得的\（{} ^ {208} \） Pb核的结果与可用的实验数据进行了比较。
