This study investigates nucleon charge-exchange reactions during carbon nucleus fragmentation at 300 MeV/nucleon, providing new experimental data to test and refine theoretical models of nucleus-nucleus interactions.

Contribution

First experimental measurement of nucleon charge-exchange processes at this energy, offering valuable data for validating theoretical models.

Findings

Measured differential cross sections for $^{11}$Be, $^{12}$B, and $^{12}$Be.

Compared experimental results with various theoretical models.

First data on charge-exchange processes at 300 MeV/nucleon.

Abstract

The search of reactions with nucleon charge-exchange was performed on the FRAGM fragment-separator of the TWAC accelerator complex at fragmentation of carbon nuclei with an energy of 300 MeV/nucleon on a thin beryllium target. The experimental setup, located at an angle of 3.5 degrees to the incident beam, had high momentum resolution. Differential cross sections were measured for $^{11}$Be, $^{12}$B and $^{12}$Be as function of the nuclei momentum. The experimental data were compared with theoretical predictions of various models of nucleus-nucleus interactions and other experimental results. Measurements of nucleon charge exchange processes in this energy region was carried out for the first time. New results were obtained to test theoretical models of nucleus-nucleus interactions.
