| 抄録: | The interaction cross sections (σI) of the very neutron-rich carbon isotopes [19]C, [20]C and [22]C have been measured on a carbon target at 307, 280, and 235 MeV/nucleon, respectively. A σI of 1.280±0.023 b was obtained for [22]C, significantly larger than for [19, 20]C, supporting the halo character of [22]C. A [22]C root-mean-squared matter radius of 3.44±0.08 fm was deduced using a four-body Glauber reaction model. This value is smaller than an earlier estimate (of 5.4±0.9 fm) derived from a σImeasurement on a hydrogen target at 40 MeV/nucleon. These new, higher-precision σI data provide stronger constraints for assessing the consistency of theories describing weakly bound nuclei. |
