CHARGE-DENSITY AND SINGLE-PARTICLE STRUCTURE - NUCLEI K-39, CA-40 AND CA-48

The charge distributions of39K,40Ca and48Ca are calculated by summing the squares of the proton wave functions in a one-body nonlocal potential, whose parameters are adjusted to give the experimental centroid energies of the single-particle states. The squared wave functions are weighted by occupation numbers. The connection between the 2 p-state occupation numbers and the diffuseness parameter of the potential is studied for the present nuclei and58Ni, whose density was calculated in a previous work. A good agreement with the «model indenendent» density is found. © 1979 Società Italiana di Fisica.
