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 Δ∼ 8 MeV at ρ∼ 0.5 ρ 0. 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.

Abstract
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 Δ∼ 8 MeV at ρ∼ 0.5 ρ 0. 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.
