At an energy of 14.5 MeV, the elastic and inelastic scattering of deuterons and the (d, t) reaction on 11B nuclei were studied. Experimental angular distributions with transitions to the states of the 11B nucleus (ground state (3/2−), 4.445 (5/2−) MeV, 6.743 (7/2−) MeV) and to the states of the 10B nucleus (ground state (3+), 0.718 MeV (1+), 1.74 MeV (0+, T = 1), 2.15 MeV (1+)) were analyzed by the coupled channel method. The value of the quadrupole deformation parameter β2= 0.80 ± 0.2 was extracted. The assumption of a direct mechanism for picking up a neutron in the reaction (d, t) made it possible to describe rather well the measured angular distributions for the states of the 10B nucleus. The values of the spectroscopic amplitudes for the transitions to these states have been extracted. It is shown that the mechanism of 8Be transfer both in the form of a whole cluster and in the sequential transfer of two α-particles does not play a significant role. It was found that the deformation of the 10B and 11B nuclei noticeably affects the calculated cross sections for the (d, t) reaction.
