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.
