- Аннотация: A novel method which allows us to find observables at many energies simultaneously in a multichannel scattering problem using just a single diagonalization of the total Hamiltonian matrix in some L(2) basis is developed. The approach is based on the multichannel generalization of ideas due to Lifshits and Birman-Krein on the tight relationship between a spectral shift function and a single-channel S matrix in the combination with L(2) discretization of the continuum. As a clear illustration for the efficiency of the suggested method, the differential cross sections of neutron scattering off heavy nuclei in the case of a complex nonlocal interaction potential as well as energy dependence of partial NN phase shifts and mixing parameters for the two-nucleon scattering with tensor force are calculated.
