STATE-SELECTIVE ELECTRON CAPTURE

Superelastic and inelastic He2++He state-selective electron capture.

State-selective electron capture in collisions of ground and metastable N2+ ions with H„1s..

An ab initio calculation of the electron capture cross sections for collisions of ground and metastable states of N2+ with Hs1sd is presented. Total cross sections are evaluated for N impact energies from 2 310−3 to 300 keV, using both quantal and semiclassical treatments. The results are compared with experimental and previous theoretical data, and are used to check the presence of metastable ...

Total and state-selective electron-capture cross sections for N-H collisions

Electron-capture cross sections in collisions of N ions with atomic hydrogen is studied using the closecoupling two-center atomic orbital expansion method by treating the collision system in a quasi-two-electron model. Total electron-capture cross sections to the dominant individual singlet and triplet excited states are evaluated over the energy range of 50–20 000 eV/amu. The results are compa...

Total and state-selective electron capture cross sections for C3+ + H collisions

Electron capture cross sections in collisions of C3+ ions with atomic hydrogen have been studied using the close-coupling two-centre atomic orbital (AO) expansion method by treating the collision system in a quasi-two-electron model. Total electron capture cross sections to the dominant individual singlet and triplet excited states are calculated over the energy range 0.1– 50 keV amu−1. The res...

Total and state-selective electron capture cross sections for B¿H collisions

Electron capture cross sections for B1H collisions are calculated using a two-center atomic orbital close coupling expansion method. Total electron capture cross sections are shown to compare well with the recent experimental data of Pieksma et al. @Phys. Rev. A 57, 1892 ~1998!# and with the molecular expansion calculation of Shimakura et al. @Phys. Rev. A 47, 3930 ~1993!#, but not with the mol...
