We analyse the contribution of isovector and isoscalar proton-neutron pairing to the binding energies of even-even nuclei with N − Z = 0, 2, 4 and atomic mass 20 < A < 100. The binding energies are calculated in the mean-field approach by coupling a Skyrme-type functional to an isovector-isoscalar pairing force of zero range. The latter is treated in the framework of quartet condensation model (QCM), which conserves exactly the particle number and the isospin. The interdependence of pairing and…
