Abstract:

An irrotational fluiddynamical method based on the generalized scaling approximation is applied to the description of isovector giant multipole states. For the case of a simple square density model for the ground state, analytic solutions of the equation of motion are derived and contrasted with those of the familiar hydrodynamical model. It is shown from model calculations that the present description provides a fair approximation to microscopic RPA results on gross features of isovector giant vibrations.
