Refractive effects in the reaction 13C(3He, t)13N at an energy of 60 MeV

In the angular range 10°–120°, the angular distributions of tritons from the reaction 13C(3He, t)13N induced by 3He nuclei of energy 60 MeV are measured for transitions to the ground state (Jπ=1/2−) of the 13N nucleus and to its excited states at Ex=2.365 MeV (1/2+) and Ex=3.51 MeV (3/2−)+3.55 MeV (5/2+). A theoretical analysis of these data is performed within the distorted-wave method under the assumption of the one-step charge-exchange mechanism. This analysis employs a microscopic form factor that takes into account the central and tensor components of nucleon-nucleon interaction. It is shown that an acceptable description of the experimental data in question is achieved with potentials whose volume integrals do not exceed 300 MeV fm3.
