The difference between neutron and proton radii in the Ca isotopes Academic Article uri icon


  • We take a close look at the recent analysis of 1 GeV proton scattering on Ca isotopes. Considering the more accurate values of relevant differences of matter and proton rms radii, a value of r n - r p = 0.10 ± 0.03 fm is obtained for 48 Ca. This value is much smaller than those quoted recently and is consistent with Coulomb displacement energies. © 1979.
