Theoretical grounds for coincidence measurements in autoionization studies

(e,2e), (e, e'gamma) and (e,2e gamma) coincidence measurements on ionizatio n of He atom via excitation and decay of (3ln'l' autoionizing states above the n=2 threshold are considered theoretically. General regularities of ali gnment transfer from atomic autoionizing states to excited states of the re sidual ion are shown under condition of strong interference between resonan t and direct ionization processes.
