Description
The isoscalar quadrupole and octupole response of heavy spherical nuclei is studied in semiclassical model that includes a coupling between the motion of nucleons and surface vibrations. An analytical expression has been obtained for the isoscalar response function of different multipolarity. The inclusion of surface vibrations leads to the low-energy modes. The low-lying quadrupole mode is strongly affected by the surface tension. The frequency of the low-lying octupole mode, instead, goes to zero for vanishing surface tension
Abstract (Russian)
Изоскалярные квадрупольные и октупольные характеристики тяжелых сферических ядер изучаются в полуклассической модели, которая включает связь между движением нуклонов и поверхностными вибрациями (ПВ). Получено аналитическое выражение для изоскалярной функции отклика разных мультиполярностей. Учет ПВ приводит к их низкоэнергетическим модам. Низколежащая квадрупольная мода сильно зависит от поверхностного натяжения ПН. Низколежащая октупольная мода уменьшается до нуля при исчезновении ПНAdditional details
