Query: Is there np pairing in odd-odd N=Z nuclei?   The binding energies of even-even and odd-odd N=Z nuclei are compared. After
correcting for the symmetry energy we find that the lowest T=1 state in odd-odd
N=Z nuclei is as bound as the ground state in the neighboring even-even
nucleus, thus providing evidence for isovector np pairing. However, T=0 states
in odd-odd N=Z nuclei are several MeV less bound than the even-even ground
states. We associate this difference with a pair gap and conclude that there is
no evidence for an isoscalar pairing condensate in N=Z nuclei.
