First application of the n- Be 9 optical potential to the study of the Be 10 continuum via the (O 18, O 17) neutron-transfer reaction

The Be9(O18,O17)Be10 reaction has been studied at an incident energy of 84 MeV, and the ejectiles have been detected at forward angles. The Be10 excitation energy spectrum has been obtained up to about 18 MeV, and several known bound and resonant states of Be10 have been identified. Calculations that describe the interaction of the neutron removed from the O18 projectile with the Be9 target by means of an optical potential with a semiclassical approximation for the relative motion account for a significant part of the Be10 continuum. Two parametrizations of the optical-model potential for the system n-Be9 have been used and compared.
