The semimicroscopic particle-hole dispersive optical model is adopted for a description of main properties of isoscalar giant multipole resonances (up to $L=3$) in medium-heavy closed-shell nuclei. The main properties are characterized by the strength distribution, transition density, and partial and total probabilities of direct one-nucleon decay. The model is implemented to describe characteristics of the mentioned resonances in the ${}^{208}\mathrm{Pb}$ nucleus, taken as an example. Calculation results are compared with available experimental data.

等重闭壳核中等量超巨子共振的性质：半微观描述

采用半微观粒子孔色散光学模型来描述等尺度超巨子共振的主要性质（直至）。 $\mathrm{大号}=3$）在中等重量的闭壳核中。主要特性的特征在于强度分布，过渡密度以及直接单核子衰变的部分概率和总概率。该模型的实现是为了描述所提到的共振的特性。${}^{208}\mathrm{铅含量}$以核为例。将计算结果与可用的实验数据进行比较。
