โฆ Synopsis
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.
