Abstract

The one- and two-neutron removal reactions from ${}^{17}C$ and ${}^{18}C$ as well as the reaction cross section of ${}^{18}C$ have been studied using a carbon target at $80 A$ MeV. The longitudinal momentum distributions of ${}^{15, 16}C$ fragments from ${}^{17}C$ and ${}^{16, 17}C$ fragments from ${}^{18}C$ were measured by a direct time-of-flight method. The width of ${}^{15}C$ fragments from ${}^{17}C$ is fairly smaller than that from other C isotopes. The experimental data are discussed within the framework of the Glauber model.
