Аннотация:The general description of simultaneous electron-impact ionization-excitation processes is reformulated in,terms of an irreducible tensor representation., Using a numerical model, in which the interaction between a ’fast’ ionizing projectile and the target is described by first- or second-order plane-wave and distorted-wave models, combined with a convergent close-coupling-type description of the initial bound state and the- interaction between a ’slow’ ejected electron and the residual ion, new benchmark calculations for the (e, e’gamma) process have been performed. The predictions are compared with recent experimental data on ionization-excitation of helium. The similarity to results’ for excitation processes and the potential extension of propensity rules is discussed.
