标题： Escape and Spreading Properties of Charge-Exchange Resonances in Bi 208

摘要： 电荷交换激发的性质，即${}^ {208}$Pb 与$\Delta L = 0$的同位素类似和 Gamow-Teller 共振，是在一个自洽模型中研究的，该模型使用了 Skyrme 类型的有效力。 众所周知的同位素类似情况被用来评估模型的可靠性。 计算得到的 Gamow-Teller 共振的性质与最近的实验测量结果进行了比较，目的是更好地理解该模式的微观结构。 显示英文摘要

摘要： The properties of charge-exchange excitations of ${}^ {208}$Pb with $\Delta L = 0$, i.e., the isobaric analog and Gamow-Teller resonances, are studied within a self-consistent model making use of an effective force of the Skyrme type. The well-known isobaric analog case is used to assess the reliability of the model. The calculated properties of the Gamow-Teller resonance are compared with recent experimental measurements with the aim of better understanding the microscopic structure of this mode.
