Effective interactions in shell-model calculations
M. Honma
The shell model is a powerful tool for studying
various nuclear properties. Its key ingredients is the
effective interaction. It has been desired that the effective
interaction can be derived microscopically from the nuclear
force. However, such an approach has not been successful
especially for cases with many valence particles. Therefore
various empirical or phenomenological aspects has been
introduced for determining the effective interaction.
I would like to talk about the problems in the microscopic
effective interactions and the possible improvements of them,
focusing especially on the case of pf-shell calculations.
In addition, I would like to discuss to what extent the
improved effective interaction can provide us a unified
description and understanding of the nuclear structure.
