Ionization in simple quasimolecules: HeH super(2) sub(2) super(+) (He super(2+) + H sub(2))

Energy spectra of electrons ejected into super(3)He super(2+)-H sub(2) collisions have been measured in the incident ion energy range 6-30 keV. Parameters of the quasimolecule formed during the collision are determined. The dominant role of the channel (2a') super(2) arrow right 1a'3a' arrow right 1a' + e in the production of electrons at keV ion energies has been revealed. The structure associated with autoionization transitions in the projectile helium atoms shows enormously large broadening and shift to lower energies.
