Isotriplet pairing energy of nucleons in nuclei

Abstract

The problem of describing the nucleon pairing energy in nuclei is considered using a realistic nucleon-nucleon potential that reproduces the parameters of nucleon-nucleon scattering. Satisfactory agreement was obtained between the calculated and experimental values of the isotriplet nucleon pairing energies for even-even nuclei. The analytical representation of the wave functions of the pair allows us to conclude that there are no signs of dineutrons or diproton clustering.
