- Abstract
The results are presented that were obtained by measuring the differential cross sections for the reaction 10B(d, p)11B occurring at Ed = 15.3 MeV and leading to the production of a 11B nucleus in the ground state (3/2–) and in the lowest two excited states (the 1/2– state at 2.125 MeV and the 5/2– state at 4.445 MeV). The energy dependence of the differential cross section for this reaction was measured for several proton emission angles in the energy range Ed = 12–15.3 MeV. The double-differential cross sections for the reaction 10B(d, pγ)11B were measured for the 5/2– state of the 11B nucleus at 4.445 MeV, and the angular dependences of the even spin-tensor components of the density matrix were reconstructed on the basis of these data. The angular dependences of the populations of magnetic sublevels are also given. The experimental results in question are compared with their theoretical counterparts obtained under the assumption of various reaction mechanisms (neutron stripping, heavy-particle stripping, and a two-step mechanism that takes into account the delay of interaction). On the basis of this comparison, the deformation parameters of the boron nuclei were found to be β2(10B) = –0.55 and β2(11B) = 0.4.© 2005 Pleiades Publishing, Inc.
