Mechanism of charge-exchange in the 7Li(10B, 10Be)7Be reaction and potential of interaction of the 7Be + 10Be nuclei
Angular distributions of the 7Li(10B, 10Bе)7Bе reaction were measured at the energy Elab(10B) = 51 MeV for the transitions to the ground and excited states of 10Bе and 7Bе nuclei. The measured 7Li(10B, 10Bе)7Bе reaction data as well as only known from the literature 10B(7Li, 7Bе)10Bе reaction data...

| Summary: | Angular distributions of the 7Li(10B, 10Bе)7Bе reaction were measured at the energy Elab(10B) = 51 MeV for the transitions
to the ground and excited states of 10Bе and 7Bе nuclei. The measured 7Li(10B, 10Bе)7Bе reaction data as well as only known from the literature 10B(7Li, 7Bе)10Bе reaction data at the energy Elab(7Li) = 39 MeV were analyzed within DWBA method for the direct charge-exchange of the 10B → 10Bе, 7Li → 7Bе nuclei and within the coupled-reactionchannels method for one- and two-step transfers of nucleons and clusters such as 10B → Х → 10Bе, 7Li → Y → 7Bе. It was studied the contributions of different mechanisms to the angular distribution of the 7Li(10B, 10Bе)7Bе and 10B(7Li, 7Bе)10Bе reactions. Using data of these reactions, the parameters of the 7Bе + 10Bе-potential as well as their
energy dependence were deduced by standard fitting procedure. The deduced 7Bе + 10Bе-potential is compared with the
corresponding folding-potential calculated using nucleon distributions in 7Bе and 10Bе. |
