Charge-exchange effects in angular resolved energy-loss spectra of HCI propagating through matter

A method of coupled integral equations for partial (charge selected) energy distributions of fast ions passing through matter suggested and successful ly used earlier to treat evolution of the shape of angular non-resolved spe ctra as a function of the foil thickness is extended to calculate unified p artial energy and angular distributions of ions passing through thin foils accompanied by multiple charge exchange processes between their different f ractions.
