Abstract
A cranked mean-field model with two-body T=1 and T=0 pairing interactions is presented. Approximate projection onto good particle-number is enforced via an extended Lipkin-Nogami scheme. Our calculations suggest the simultaneous presence of both T=0 and T=1 pairing modes in N=Z nuclei. The transitions between different pairing phases are discussed as a function of neutron/proton excess, T$_z$, and rotational frequency, $\hbar\omega$. The additional binding energy due to the T=0 $np$-pairing correlations, is suggested as a possible microscopic explanation of the Wigner energy term in even-even nuclei.
