Shell Structure of theNi58Charge Density

Abstract

A very-high momentum-transfer ($q=780\mathrm{}$ MeV/c), elastic electron-scattering experiment on ${}_{}{}^{58}{}_{}{}^{}\mathrm{Ni}$ has been performed using the 600-MeV linac of Saclay. The charge density, extracted from ($e, e$) and muonic-x-ray data, exhibits considerably less structure than predicted by Hartree-Fock calculations.
