    "abstract": "The binding energies of even-even and odd-odd N=Z nuclei are compared. After\ncorrecting for the symmetry energy we find that the lowest T=1 state in odd-odd\nN=Z nuclei is as bound as the ground state in the neighboring even-even\nnucleus, thus providing evidence for isovector np pairing. However, T=0 states\nin odd-odd N=Z nuclei are several MeV less bound than the even-even ground\nstates. We associate this difference with a pair gap and conclude that there is\nno evidence for an isoscalar pairing condensate in N=Z nuclei.",
