Electron momentum distribution in multiply-ionized atoms as a function of atomic number and degree of ionization

Abstract

We present momentum-space properties of multiply ionized atoms as a function of atomic number Z and the degree of ionization of the atom. In particular, we have calculated the Compton profiles of all possible electronic configurations of He, Li, Be, B and N atoms as they are progressively ionized with the outer-shell electrons being stripped off. The values of the Compton profiles presented here can be used to deduce doubly differential cross-sections of variously ionized atoms colliding with other atoms and ions. The single-electron radial wavefunctions were obtained from the Hartree-Fock atomic model. Compton profiles of neutral atoms, available in the literature, are in excellent agreement with the present calculation.
