Electron-impact state-to-state cross sections and rate coefficients X(v) -> B(v') for excitation of LiH molecule

Electron-impact cross sections for the v->v'\rightarrow v^{\prime}$ transitions between the vibrational levels of $X^1\Sigma^+$ and the excited $B^1\Pi$ electronic states of LiH molecule, are calculated from threshold to 1000 eV by using the threshold-modified Mott-Massey approximation. Cross sections for the dissociative process, occurring through the excitation to the continuum spectrum of the vibrational levels of the B state, are also obtained. Maxwellian rate coefficients for the corresponding $bound-to-bound$ and $bound-to-continuum$ transitions are presented in the temperature range of 0.1-10 000 eV. Finally, scaling relationships for both the $v-v^{\prime}$ cross section and rate coefficients are derived in order to represent the calculated quantities in a compact analytic form.
