Resumo
A large yield of α particles produced in the 120Sn(6He, α) reaction was measured at 20.3-, 22.2-, 22.4-, and
24.5-MeV bombarding energies. The α particles are distributed over a broad energy range in the vicinity and
below the elastic scattering 6He peak. Energy integrated α-particle cross sections have been obtained at θlab =
36◦, 40◦, and 60◦. The α energy distributions have been analyzed at a fixed laboratory angle (≈60◦) in terms of
the reaction Q value, considering the 2n-transfer reaction kinematics 120Sn(6He, α)122Sn. A kinematical analysis
of the Q-value distribution shows that the recoil system 120Sn + 2n is formed in highly excited states in the
continuum, at increasing excitation energies as the bombarding energy increases. It is shown that by using Brink’s
formula, the excitation energy depends on the transferred angular momentum following a linear relation with the
square of the angular momentum, indicating that some kind of dinuclear rotating system is formed after the
reaction.
