Fully-stripped-beryllium-ion collisions with 2ℓm states of atomic hydrogen: Total and state-selective electron-capture cross sections
TL;DR: In this article , the wave-packet convergent close-coupling approach was used to solve the three-body Schrodinger equation by employing a two-center expansion for the total scattering wave function, and the results indicated that at low energies, collisions with hydrogen in each of the states produced a total electron capture cross section approximately an order of magnitude larger than for scattering on the ground state.
