Skyrme Interaction with Attractive Pairing Property without Density Dependent Force

• 論文の詳細を見る

• We propose some parameter sets of the Skyrme interaction with additional two spin exchange terms to reproduce the pairing matrix elements. The effects are difficult to be reproduced by the original Skyrme interaction due to the strong repulsion caused by the three-body force. Therefore density dependent forces have generally been used instead of the three-body one, but the density dependent forces give rise to fundamental ambiguities. Though the parameter sets in our work may not exhibit realistic properties enough, after refinement, we hope the Skyrme force (which is revised on the line of this paper) will prepare a handy tool for re-investigating nuclear properties.
