Wave-packet evolution approach to ionization of the hydrogen molecular ionby fast electrons - art. no. 062711

The multifold differential cross section of the ionization of hydrogen mole cular ion by fast-electron impact is calculated by a direct approach, which involves the reduction of the initial six-dimensional (6D) Schrodinger equ ation to a 3D evolution problem followed by the numerical modeling of the w ave-packet dynamics. This approach avoids the use of stationary Coulomb two -center functions of the continuous spectrum of the ejected electron that d emands cumbersome calculations. The results obtained, after verification of the procedure in the case of atomic hydrogen, reveal interesting mechanism s in the case of small scattering angles.
