The DIM method IS used to compute the resonant energy and the autoionization width for a wide range of confguratlons of the He(2 %)-HZ system. The calculations reveal possible non-admbatlc characrer of the Penrung ~onl~amn ar hgher He(2 3S)-H, colhsion energies The DIM model is found to be apable of
We present angle-dependent electron energy spectra due to ionizing collisions of metastable He\*(2 'S) atoms with groundstate hydrogen and deuterium atoms. The data, measured at thermal collision energies (I?,,, = 50 meV), show an angular variation of the spectral shape which is well reproduced by a
