T=0andT=1pair correlations inN=Zmedium-mass nuclei

The isospin generalized BCS equations and the Hartree-Fock-Bogoliubov equation are solved for the ground states of even $N=Z$ nuclei with mass number $A=76\mathrm{}-96.$ The calculations include isospin $T=1\mathrm{}$ ($pp,$ $nn,$ and $\mathrm{np}$) pair correlations as well as isospin $T=0\mathrm{}$ $\mathrm{}\left(\mathrm{np}\right)\mathrm{}$ pair correlations. There is a transition from $T=1\mathrm{}$ pairing at the beginning of this isotope sequence to $T=0\mathrm{}$ pairing at the end of the sequence, with the possibility of a mixed phase containing both $T=0\mathrm{}$ and $T=1\mathrm{}$ pairing near the middle of the sequence.
