Abstract: Isobaric and isotopic effects were investigated in the angular distributions of the 9Ве(11В, 12B)8Be and 9Ве(11В, 12C)8Li, 9Ве(11В, 12B)8Be and 9Ве(11В, 10B)10Be reactions at the energy Еlab(11В) = 45 MeV. The experimental data of the 9Ве(11В, 12B)8Be and 9Ве(11В, 10B)10Be reactions measured earlier, were used. The angular distribution of the 9Ве(11В, 12C)8Li reaction were measured at Еlab(11В) = 45 MeV for the transitions to the ground states of 12C і 8Li and to the 4.439 MeV (2+) state of 12C and 0.981 MeV (1+), 2.261 MeV (3+), 3.21 MeV (1+), 5.4 MeV (2+) states of 8Li. The data were analyzed within the coupled-reaction-channels method. It was found existence of considerable difference (isobaric effect) in the angular distributions of the 9Ве(11В, 12B)8Be and 9Ве(11В, 12C)8Li reactions. The isotopic effects in the angular distributions of the 9Ве(11В, 12B)8Be and 9Ве(11В, 10B)10Be reactions at the energy Еlab(11В) = 45 MeV were investigated. The isotopic and isobaric effects in the optical potentials of the 11B + 9Be, 10B + 10Be, 12B + 8Be, 12C + 8Li nuclear interactions were analyzed.
