Title:Solving scattering problems by using spectral methods

Time:10:00 am, October 11th (Thursday), 2018

Location:Main building 513

Abstract:

The efficient technique for treating scattering problems by using the discretized spectral expansion for the total Hamiltonian is discussed. Here the stationary wave packet formalism is employed and a diagonalization procedure for the total Hamiltonian in such a basis. As a result, multi-channel off-mass-shell T-matrix and scattering amplitudes are found at many energies simultaneously without solving any scattering equations at all.As illustrations, some examples from atomic and nuclear physics are presented.
