Abstract

We present the results of calculations determining the cross sections for indirect dissociative recombination of LiH2+_2^+ + ee^-. 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.\cite{hamilton}. We use \textit{ab initio} electron-molecule scattering codes to calculate quantum defects. In contrast to H3+_3^+, the LiH2+_2^+ molecule exhibits considerable mixing between rotation and vibration; however, by incorporating an exact treatment of the rovibrational dynamics of the LiH2+_2^+, 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 ×\times 107^{-7} cm3^{3} s1^{-1} at 1 meV incident electron energy.
