Microscopic analysis of image and image proton–neutron correlations in image nuclei Original Research Article

The competition between the isovector (T=1) and isoscalar (T=0) proton–neutron (p–n) correlations in N=Z nuclei is investigated by calculating their correlation energies with a realistic effective interaction which reproduces observed nuclear properties very well, in a strict shell model treatment. It is shown in the realistic shell model that the double-differences of binding energies View the MathML source (B(A) being the binding energy) are good indicators of the T=1 and T=0p–n correlations. Each of them, however, originates in plural kinds of correlations with T=1 or T=0.
