Nuclear pairing in the T=O channel reexamined - art. no. 037304

Recent published data on the isoscalar gap in symmetric nuclear matter usin g the Paris force and the corresponding BHF single particle dispersion are corrected, leading to an extremely high proton-neutron gap of Delta similar to8 MeV at rho similar to 0.5 rho (0). Arguments of whether this value can be reduced due to screening effects are discussed. A density dependent del ta interaction with cutoff is adjusted so as to approximately reproduce the nuclear matter values with the Paris force.
