The role of various mechanisms in the formation of the 12B nucleus in the 10B(t, p)12B reaction

Mechanisms of sequential particle transfer and characteristics of light neutron-excess and oriented nuclei

“…(34), (53) [81]: neutron pickup ( 13 C → n + 12 C(0 + , 2 + )), exchange by a heavy cluster 9 Be ( 13 C → 9 Be + α), ditto with 8 Be ( 12 C(0 + , 2 + ) → 8 Be + α). As is seen from the table, these factors for each state of final nucleus 12 C are the quantities of the same order, so that it can be expected in advance that the contributions to the reaction cross section from all three mechanisms will be substantial.…”

“…The computation allowed one to produce a quali tative description of experimental values for ρ kκ (θ α ) in the forward hemisphere, although detailed agreement with experiment was not achieved. In [81] we evalu ated differential cross sections of the reaction 13 C( 3 He, α) 12 C(0 + ; 2 + , 4.443 MeV) and statistical ten sors ρ kκ (θ α ) for the mechanisms of neutron pickup and exchange by a heavy cluster 9 Be.…”

“…(57) by coherently summing up the matrix elements of both mechanisms considered. The optical potential parameters in the initial and final channels are taken the same as in [49] ( Table 2).…”

“…In [49], we calculated the cross section of the reac tion 10 B(t, p) 12 B with taking into account the pole mechanisms of dineutron stripping, as well as the mechanism of sequential transfer of two neutrons (Fig. 13).…”
