Interfering Doorway States and Giant Resonances I: Resonance Spectrum and Multipole Strengths

Interfering Doorway States and Giant Resonances I: Resonance Spectrum and Multipole Strengths

Show other versions (1)

Using a phenomenological schematic model of multipole giant resonances we consider the effects of overlapping of their doorway components. The conccpt of the partial widths of a giant resonance becomes ambiguous when the escape widths get comparable with the spacings between the components. In such...
