Direct-decay properties of Giant Resonances

Abstract

A semi-microscopic approach based on the continuum-RPA method and a phenomenological treatment of the spreading effect is developed and applied to describe direct-decay properties of a few isovector giant resonances. Capabilities of the approach to describe giant-resonance gross properties are also checked.
