Coulomb displacement energies in the shell

The experimental Coulomb displacement energies in the shell (except one) can be described by Hecht's Coulomb energy equation with a standard deviation of 8.5 keV if it is assumed that the Coulomb interaction radius is 2.6+/-0.5% larger for the completely filled shell than it is for the unfilled shell. The standard error of the calculated energies is 1.8 keV. Electromagnetic spin-orbit effects are indicated. The two Coulomb interaction energies V0 and which were obtained from the least-squares analysis are in very good agreement with the theoretically predicted values. The energy of the 0+, T = 1 ground state of 42Sc is too low and deviates by about 45 keV from the expected value.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/33157/1/0000543.pd
