摘要: Abstract Differential cross section and analyzing-power angular distributions have been measured for protons elastically scattered from 40, 44, 48Ca at energies in the range of 10.8–16.3 MeV. Optical-model fits used to obtain rms radius real-central potential each nucleus energy. Mean square radii neutron obtained an expression which relates mean proton distributions, potential, triplet singlet nucleon-nucleon interactions. The differences 〈r n 2 〉 1 −〈r p = Δ , as determined this analysis are +0.01±0.14, −0.02±0.12, +0.39±0.10 fm 48Ca, respectively.
