Ion-electron coincidence measurements of the azimuthal dependence of electrons from autoionizing He atoms excited in 2000-eV He+-He collisions

Journal Article

The azimuthal angular dependence and corresponding energy spectra have been measured for electrons ejected at 135° from the beam direction by autoionizing He atoms in the (2p2)D1 and (2s2p)P1 states, which were excited by 2000-eV He+ ions scattered through 6°. The data show a marked dependence on the azimuthal angle of the scattered projectile and are used to calculate the moduli and phases of the population amplitudes of the magnetic sublevels excited. © 1978 The American Physical Society.
