Is There Neutron Proton Pairing in Medium Heavy-Nuclei

Artikel i vetenskaplig tidskrift, 1984

Present knowledge of the proton and neutron pairing energies Δp and Δn, deduced from nuclear masses, is reviewed and an attempt is made to find general trends in the data. The analysis shows that, besides the well-known smooth slow decrease with A, the pairing energies also contain a symmetry energy-like dependence on the neutron excess View the MathML source. The trends is most pronounced in the shell 50
