摘要

A finite-temperature fluid-dynamical model of the nucleus has been investigated. The model allows for surface modes with an excitation energy which is directly related to the surface tension. The currents associated with these modes have strong transverse components. We show that, as a result of thermal fluctuations, a new sound velocity appears, which is not present at zero temperature, and, as a consequence, new eigenmodes also appear. While the energies are stable, when we take the limit T --> 0, the strength corresponding to these new eigenmodes tends to zero. Electric and magnetic modes are studied. The spectrum of excited energies and the currents are calculated for a nucleus with mass number A = 208. The present model predicts a sizable redistribution of transition strength when the temperature is increased. [References: 29]
