Description

This work presents the results of single and double charge exchange reactions measuring in the fragmentation of carbon ions at the energy of 300 MeV/nucleon. Experimental data were collected at the FRAGM facility and the ITEP-TWAC multi-purpose accelerator complex on a thin beryllium target [1, 2]. The search was made for the following set of isotopes that carried out with nucleon charge exchange: ¹¹Be, ¹²B, ¹²N, ¹²Be. The differential cross sections for the production of these isotopes considered as functions of the fragment momentum [3]. These measurements of the charge exchange processes in this energy range were performed for the first Time. Additionally the upper limit of the ¹²N ions production was also estimated. The obtained data are considered with a comparison of the theoretical ion-ion interaction models. These presented results expand the database on nuclear fragmentation processes that occur with nucleon charge exchange and provide new material for testing the theoretical models.
