The mechanism of the (alpha, Li-6)-reactions was studied by using B-10
, N-14,N-15, and F-19 target nuclei and an alpha-particle beam of 27.2
MeV energy. The obtained contribution estimations of the statistical-
and direct-process of two-nucleon cluster transfer to the reaction cr
oss-sections were used in the attempt to describe the experimental dat
a. The spectroscopic factors of the studied cluster configurations for
the B-10, N-14,N-15 and F-19 nuclei were obtained.
