Abstract
The elastic and inelastic scatterings of [Formula: see text]-particles were investigated at an energy of 40[Formula: see text]MeV with excitation of low-lying states of the [Formula: see text]B nucleus [0.0 (3/2[Formula: see text]), 4.445 (5/2[Formula: see text]), 6.74 (7/2[Formula: see text]), 2.125 (1/2[Formula: see text]) and 5.02[Formula: see text]MeV (3/2[Formula: see text])]. The analysis of the experimental angular distributions was carried out via the coupled channels method within the framework of the collective model. The value of the quadrupole deformation parameter [Formula: see text] was extracted. Calculations indicate a preference for a negative sign for deformation. It is shown that the exchange mechanism with the transfer of the heavy 7Li cluster does not play an important role in the scattering of [Formula: see text]-particles on [Formula: see text]B nuclei at an energy of 40[Formula: see text]MeV.
