Abstract

Angular distributions of the 7Li(10B, 9Bе)8Bе were measured at the energy Elab(10B) = 51 MeV (21 MeV c.m.) for the ground and excited states of 8Bе. The experimental data were analyzed within the coupled-reaction-channels (CRC) method for one- and two-step transfers of nucleons and clusters. The 10B(7Li, 9Bе)8Bе reaction data at the energy Elab(7Li) = 24 MeV (14,12 MeV c.m.) known from the literature, were included in the CRC-analysis also. Mechanism of the reactions was determined, the parameters of the 8Bе + 9Bе-potential were deduced and energy dependence of the parameter was studied.

Abstract

Angular distributions of the 7Li(18O, 17N)8Be reaction were measured for the transitions to the ground states of 8Be and 17N and excited states of 17N at the energy Elab(18O) = 114 MeV. The data were analyzed with coupled-reaction-channels method for one- and two-step transfers of nucleons and clusters. In the analysis, the 7Li + 18O potential de-duced in the analysis of the elastic 7Li + 18O-scattering data as well as shell-model spectroscopic amplitudes of trans-ferred nucleons and clusters were used. Parameters of the 8Be + 17N potential were deduced using the reaction data. Contributions of different one- and two-step transfers in the 7Li(18O, 17N)8Be reaction cross-section was studied.

Abstract

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.
