Contribution

It introduces a folding-model approach to analyze the reaction cross sections of helium isotopes on carbon at high energy, assessing its accuracy and applicability.

Findings

The folding model reproduces experimental cross sections well.

The model provides insights into the nuclear structure of helium isotopes.

Comparison with Glauber model shows competitive accuracy.

Abstract

Tanihata {\it et al.} determined matter radii $r_{m}(\sigma_{\rm I})$ for $^{4,6,8}$He from interaction cross sections $\sigma_{\rm I}$ of $^{4,6,8}$He+$^{12}$C scattering at 790 MeV per nucleon, using the optical limit of the Glauber model. Lu {\it et al.} determined proton radii $r_{p}({\rm AIS})$ for $^{4,6,8}$He with the atomic isotope shifts (AIS). We investigate whether the Love-Franey $t$-matrix folding model is good for $^{4,6,8}$He+$^{12}$C scattering at 790 MeV per nucleon.
