State-selective electron capture in collisions of ground and metastable O² ions with H(1s)

Abstract

An ab initio calculation of the electron capture cross sections for collisions of ground and metastable states of O2+ with H(1s) is presented. For impact energies between 0.125 and 3.4 keV amu−1, we find good agreement between the cross sections from the ground state ion with the mixed beam experimental data of Phaneuf et al (Phaneuf A, Alvarez I, Meyer F W and Crandall D H 1982 Phys. Rev. A 26 1892).

“…Charge transfer plays an important role in a variety of environments and therefore has seen a substantial amount of activity over the report period. Studies for collisions on H include: Cabrera-Trujullo et al 2002a, Celiberto et al 2002, Killian et al 2004, He 2+ (Le et al 2004), Li +−3+ (Purkait 2003), Li 3+ and Ne 10+ (Errea et al 2004b), B 2+ (Turner et al 2003), C 4+ , C 4,5+ , N 5,6+ , and O 6,7+ (Kearns et al 2003), N + (Lin et al 2005), N 2+ ( Barragan et al 2004), N 4+ (Cabrera-Trujillo et al 2002c), N 5+ (Kearns et al 2002), O + (Spirko et al 2003), O 2+ (Cabello et al 2003), O 3+ (Wang et al 2003), O 8+ and Ar 8+ (Edgu-Fry et al , Lee et al 2004, Ne 2+ (Mroczkowski et al 2003), Ne 3+ (Rejoub et al 2004), and Ne 4+ (Havener et al 2004). Collisions of neutral species with protons include: He * (Chibisov et al 2002), N (Lin et al 2005), Na (Watanabe et al 2002, S (Zhao et al 2005a), Ar (Kirschner et al 2004), and K (Watanabe et al 2002, Hayakawa et al 2004.…”
