Abstract:
In this work, the mechanisms of the three-nucleon cluster transfer in the nuclear
reaction 3He(9Be, 6Be)6He are studied. The theoretical model suggests that three neutrons
are transferred through two-step transfer mechanisms: n-2n and 2n-n. At the same time,
the transfer of the 3He cluster in this nuclear reaction goes through inverse kinematics. The
Coupled reaction channels (CRC) method is applied for the theoretical analysis of the nuclear
reaction. The spectroscopic amplitudes for overlap function included in calculations of onestep and two-step reactions have been extracted. Comparisons of the obtained amplitudes with
other sources are given. Calculation of the resulting model for the differential cross section of the
reaction 3He(9Be, 6Be)6He shows good agreement with experimental data under the condition
of factorization of certain overlap functions.
