Study of orientation characteristics of the 11B(5/2−, 4.445 MeV) nucleus in the 13C(d, αγ)11B reaction at E d = 15.3 MeV

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

“…and statistical tensors of the 11 B(5/2 -nucleus) Experimental differential cross sections for this reaction with production of 11 B in the ground and three lowest excited states are obtained in [73,74]. The theoretical analysis of experimental results enabled determination of a contribution to the cross section of the reaction, studied from the more involved mecha nisms than just a deuteron cluster pickup.…”

“…31 corre sponds to the particle stripping mechanism. The matrix element of the latter М 2 (without considering the constant normalization factors) has the form sim ilar to the expression given in (74) for the lower part of a whole diagram, up to replacement of the decay widths for respective nuclei:…”

“…The theoretical cross sections are calculated [73,74] assuming direct mechanisms represented by the diagrams in Fig. 24 to take place, along with the mechanism of compound nucleus formation [75][76][77].…”

“…Experimental data are borrowed from[74]. Curves-calculations for various reaction mechanisms assumed: dashed one-deuteron pickup in CCM, crosses-heavy particle stripping, dotted curve-coher ent sum of mechanisms of heavy particle stripping and sequential cluster transfer, solid one-sum of all mecha nisms.…”
