Indirect dissociative recombination of LiH2+ + e-
Abstract
We present the results of calculations determining the cross sections for indirect dissociative recombination of LiH2+ + e-. These calculations employ multichannel quantum defect theory and Fano's rovibrational frame transformation technique to obtain the indirect DR cross section in the manner described by Ref.hamilton. We use ab initio electron-molecule scattering codes to calculate quantum defects. In contrast to H3+, the LiH2+ molecule exhibits considerable mixing between rotation and vibration; however, by incorporating an exact treatment of the rovibrational dynamics of the LiH2+, we show that this mixing has only a small effect on the observed DR rate. We calculate a large DR rate for this cation, 4.0 × 10-7 cm3 s-1 at 1 meV incident electron energy.
