Název v původním jazyce

Ternary recombination of excited Ar+(2P1/2) ions. II. Internal states of nascent Ar2+ and a novel view on the elementary recombination processes

Popis výsledku v původním jazyce

Electronic states and internal energies of stabilized Ar-2(+) ions resulting from ternary collisions of Ar+(P-2(1/2)) with argon atoms are analyzed at close to thermal conditions (E/N = 1 Td). For the former, a quasiadiabatic behavior has been observed with the electronic states of the stabilized dimer ions almost exclusively asymptotically correlating to the P-2(1/2) state of the colliding atomic ion. Transitions to the electronic states with the P-2(3/2) asymptote are of only marginal importance. The internal energies of stabilized dimer ions are found around the (2)P(1/2 )dissociation limit, with a non-negligible number of the ions formed in rotationally metastable states. The calculations performed for Ar+(P-2(1/2)) are compared with selected data obtained for Ar+(P-2(3/2) ). Qualitatively, the same behavior is seen for both types of ions. The results obtained for both types of Ar+ ions lead us to the conclusion that the simple picture of the ternary recombination of Ar+ ions generally shared in the literature will have to be replaced by a more complex one.
