Abstract

The reaction cross section ($\sigma_R$) of the very neutron-rich carbon isotope $^{22}$C has been measured on a carbon target at 235 MeV/nucleon. A $\sigma_R$ of $1.280 \pm 0.023$ b was obtained for $^{22}$C, significantly larger than those for the neighboring isotopes, supporting the halo character of $^{22}$C. A $^{22}$C root-mean-squared matter radius of $3.44 \pm 0.08$ fm was deduced using a four-body Glauber reaction model. This value is smaller than an earlier estimate of $5.4 \pm 0.9$ fm derived from a $\sigma_R$ measurement on a hydrogen target at 40 MeV/nucleon.
