Neutron removal reactions of¹⁷C

Measurement of one-, two- and three-neutron removal cross sections of ¹⁷C at 79 A MeV on a ¹²C target has been carried out using the fragment separator RIPS of RIKEN. The one-neutron removal cross sections were compared with the few-body Glauber calculations coupled with the spectroscopic factors from the shell model. A fair agreement between the calculation and the experimental data was found. The prediction of the relation between the reaction cross sections and one-neutron removal cross section can be well satisfied, which means that ¹⁷C could be described by a core plus valence neutron system. The two- and three-neutron removal cross sections of ¹⁷C are reported for the first time.
