Аннотация
The $^{9}\mathrm{Be}(^{18}\mathrm{O},^{17}\mathrm{O})^{10}\mathrm{Be}$ reaction has been studied at an incident energy of 84 MeV, and the ejectiles have been detected at forward angles. The $^{10}\mathrm{Be}$ excitation energy spectrum has been obtained up to about 18 MeV, and several known bound and resonant states of $^{10}\mathrm{Be}$ have been identified. Calculations that describe the interaction of the neutron removed from the $^{18}\mathrm{O}$ projectile with the $^{9}\mathrm{Be}$ target by means of an optical potential with a semiclassical approximation for the relative motion account for a significant part of the $^{10}\mathrm{Be}$ continuum. Two parametrizations of the optical-model potential for the system $n\text{\ensuremath{-}}^{9}\mathrm{Be}$ have been used and compared.
