T=0 neutron-proton pairing correlations in the superdeformed rotational bands around Zn-60

• The superdeformed bands in Cu-58, Cu-59, Zn-60, and Zn-61 are analyzed within the frameworks of the Skyrme-Hartree-Fock as well as Strutinsky-Woods-Saxon total Routhian surface methods with and without T = 1 pairing correlations between like particles. It is shown that a consistent description within these standard approaches cannot be achieved. A T = 0 neutron-proton pairing configuration mixing of signature-separated bands in Zn-60 is suggested as a possible solution to the problem.
