Popis: Background:: The neutron skin thickness RskinPVof PREX-II is presented in Adhikari et al. (2021). The reaction cross section σRis useful to determine the matter radius Rmand Rskin. For proton scattering, the reaction cross section σRare available for Elab˜>400MeV. Methods and results:: We determine Rnexp=5.727±0.071fm and Rmexp=5.617±0.044fm from Rpexp= 5.444 fm and RskinPV. The RpGHFBcalculated with Gongny-D1S HFB (GHFB) with the angular momentum projection (AMP) agrees with Rpexp. The neutron density calculated with GHFB+AMP is scaled so as to Rnscaling=5.727fm. The Love-Franey t-matrix model with the scaled densities reproduces the data on σR. Aim:: Our aim is to find the σRof proton scattering consistent with RskinPV. Conclusion:: The σRof proton scattering consistent with RskinPVare σRexpat Elab=534.1,549,806MeV.
