Abstract

Background: The neutron skin thickness R_skin^PV of PREX-II is presented in Adhikari et al. (2021). The reaction cross section σ_R is useful to determine the matter radius R_m and R_skin. For proton scattering, the reaction cross section σ_R are available for E_lab˜>400MeV. Methods and results: We determine R_n^exp=5.727±0.071 fm and R_m^exp=5.617±0.044 fm from R_p^exp = 5.444 fm and R_skin^PV. The R_p^GHFB calculated with Gongny-D1S HFB (GHFB) with the angular momentum projection (AMP) agrees with R_p^exp. The neutron density calculated with GHFB+AMP is scaled so as to R_n^scaling=5.727 fm. The Love-Franey t-matrix model with the scaled densities reproduces the data on σ_R. Aim: Our aim is to find the σ_R of proton scattering consistent with R_skin^PV. Conclusion: The σ_R of proton scattering consistent with R_skin^PV are σ_R^exp at E_lab=534.1,549,806MeV.
