Measurements of the Elastic and Inelastic Scattering Cross Sections of ¹³C Ions on ¹²C Nuclei at the Near Coulomb Barrier Energy

Abstract

Differential cross sections for elastic scattering of 13 C ions on the nuclei 12 C were measured using extracted beam from the cyclotron K=160 HIL (Warsaw University) in wide range of angles at energy 2.5 MeV/nucleon. The angular distribution showed almost monotonic decrease of the cross sections at forward hemisphere. An increase in differential cross section starting from intermediate angles is predicted by coupled channels calculations.
