Abstract [en]

The structures of odd-odd N = Z nuclei in the lower fp shell have been investigated with a new microscopic interaction. The interaction is derived from a high-precision charge-dependent Bonn nucleon-nucleon potential using the folded-diagram renormalization method. Reasonable agreements with experimental data have been obtained. Particularly, the relative positions of T = 0 and T = I bands are well reproduced. As examples, the spectroscopies and isospin structures of (46)V and (50)Mn have been discussed in details, with the useful predictions of level structures including electromagnetic properties. Some unique features in these nuclei can be used to increase the understanding of the effective interaction theory. Our calculations show that the realistic effective interaction which is directly related to nucleon-nucleon scattering can give the reasonable descriptions of the collective properties of nuclear many-body system without any empirical modification.
