Abstract

Recent developments of the wave-packet continuum discretization approach are presented. A treatment of the Hamiltonian’s pseudostates as approximations for stationary wave packets allows to evaluate the total resolvent and the transition operator by using a diagonalisation of the Hamiltonian matrix in some appropriate \(L_2\) basis. The approach is shown to be very useful for studying continuous spectrum problems in medium, in particular, for infinite nuclear matter. As a result, the reaction matrix for different relative momenta and different energies can be found by using a single diagonalisation procedure which simplifies drastically self-consistent calculations for the equation of state in infinite nuclear matter.
