Differential ion-pair prodllction cross sections for Ar\* -12 collisions at center of mass energies of 25-133 eV are quite similar to analogous alkali-12 results despite the addition of compering channels (Penning ionization and excitation transfer) and possibIe multiple electronic surface crossings

โฆ Synopsis
Energy spectra of electrons ejected in coltisions of He metastablcs with Xe are measured For laboratow collision energies of He ranging from 30 eV up to SO0 eV. It is shown that in tflis range the ionization process changes frOJI1 Penning ionization IO excitation transfer foltowed by atomic ~utoion~tiorl of Xc.

Measurements have been made of the vibrational branching ratio iv = O)/(u' = 1) in Nz (C ' l$) formed in electronic energy transfer collisions between argon metastable atoms and ground state nitrogen molecules, using crossed molecular beams. In the relative collision energy range, 0.08-0.20 eV, this
