Theoretical study of the ionization of orbital-polarized p-excited alkali atoms by electron impact. 3D representation of the results

The Born-Coulomb approximation was used to study the electron impact ionization of p-excited Li and Na atoms with a given projection m of the orbital angular momentum on a specified axis. The wave function of the initial state of the atom electron was calculated using the effective charge approximation. The transformation of the initial wave function upon rotation of the coordinate system was considered. An analytical expression for the ionization amplitude was derived. Numerical results for the angular distributions of double differential cross sections of ionization were represented in the form of three-dimensional images.
