摘要

In the angular range 10°-120°, the angular distributions of tritons from the reaction ~(13)C(~3He, t)~(13)N induced by ~3He nuclei of energy 60 MeV are measured for transitions to the ground state (J~π = 1/2~-) of the ~(13)N nucleus and to its excited states at E_x = 2.365 MeV (1/2~+) and E_x = 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 fm~3.
