The superdeformed bands in ^{58}Cu, ^{59}Cu, ^{60}Zn, and ^{61}Zn
are analyzed within the frameworks of the Skyrme-Hartree-Fock as well as
Strutinsky-Woods-Saxon total routhian surface methods with and without the
*T*=1 pairing correlations. 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 ^{60}Zn is
suggested as a possible solution to the problem.
