Recent published data on the isoscalar gap in symmetric nuclear matter using the Paris force and the corresponding BHF single particle dispersion are corrected, leading to an extremely high proton-neutron gap of \ensuremathΔ\ensuremath∼8 MeV at \ensuremathρ\ensuremath∼0.5\ensuremathρ0. Arguments of whether this value can be reduced due to screening effects are discussed. A density dependent delta interaction with cutoff is adjusted so as to approximately reproduce the nuclear matter values with the Paris force.
