摘要

A method for calculating multistep direct reactions for both continuum and discrete levels is proposed. The energy-angle correction scattering kernel is adopted for continuum and discrete levels in the semiclassical approach, in which the angular momentum and parity conservations are considered. The Legendre coefficients of the angular distributions are calculated based on one-step distorted wave Born approximation in stead of nucleon- nucleon scattering expressions in nuclear matter. The calculated discrete level neutron angular distributions of ~(11)B(p, n_0)~(11)C reaction and the cross sections of ~(11)B(p, n_0) ~(11)C and ~(11)B(p, n)~(11)C reactions reproduce the experimental data reasonably. This approach can also be used for composite particle emissions.
