Matter radii and skins of 6,8 He from reaction cross section of proton+6,8He scattering based on the Love–Franey t-matrix model

Background:: For 4,6,8He, Tanihata et al. determined matter radii rm(σI)=1.57(4),2.48(3),2.52(3) fm from interaction cross sections σIfor 4,6,8He scattering on Be, C Al targets at 790 MeV/nucleon. Lu et al. measured the atomic isotope shifts (AIS) for 4,6,8He and determined proton radii rp(AIS)for 4...

description Background:: For 4,6,8He, Tanihata et al. determined matter radii rm(σI)=1.57(4),2.48(3),2.52(3) fm from interaction cross sections σIfor 4,6,8He scattering on Be, C Al targets at 790 MeV/nucleon. Lu et al. measured the atomic isotope shifts (AIS) for 4,6,8He and determined proton radii rp(AIS)for 4,6,8He. As for p+4,6,8He scattering, reaction cross sections σR(exp)are available at 700 MeV with high accuracy. Aim:: Our aim is to determine matter radii rmand skins rskinfor 6,8He from the σR(exp)and the rp(AIS). Method:: Our model is the Love–Franey t-matrix folding model, since the model is better than the optical limit of Glauber model. Results:: Our results for 6,8He are rm(exp)=2.48(3),2.53(2) fm and rskin=0.78(3), 0.82(2) fm. Conclusion:: For 6,8He, our results rm(σR)agree with those of Tanihata et al.. For 8He, the distance between 4He and the center of mass of valence four neutrons is 2.367 fm.
