Abstract

The modified finite temperature random phase approximation (modified FT-RPA) has been constructed with taking the influence of thermostat on the structure of quansiparticles into account. The modified FT-RPA linear response for electric quadrupole ({lambda}{sup {pi}} = 2{sup +}) and octupole ({lambda}{sup {pi}} = 3{sup -}) excitations in {sup 5}8Ni has been calculated as a function of the nuclear temperature. As compared to the conventional FT-RPA the modified FT-RPA has given a stronger spreading for the strength distribution of quandrupole excitations at finite temperature T {<=} 3MeV. (author). 22 refs; 4 figs; 2 tabs.
