Autoionization spectra of He excited by fast (MeV) H/sup +/, He/sup +/, and Li/sup n//sup +/ (N = 1,2,3) ions
Autoionization spectra of He following excitation by 1 to 3 MeV H/sup +/, He/sup +/, and Li/sup n//sup +/ (n = 1,2,3) have been measured as a function of observation angle. The (2p/sup 2/)/sup 1/D and (2s2p)/sup 1/P resonances have been examined and a strong dependence on projectile velocities, charge state and observation angle was found. The measurements were performed in a crossed-beam scattering chamber. The target-gas pressure was in the order of 10/sup -4/ Torr. The secondary electrons have been energy analyzed by a 45/sup 0/ parallel-plate analyzer. Results are presented and discussed. (WHK)
