Electron-impact state-to-state cross sections and rate coefficients for $X\left(v\right)\to A\left(v^{\prime }\right)$ excitation of LiH molecule

Electron-impact cross sections for the $v\to v^{\prime }$ transitions between the vibrational levels of X ¹Σ⁺ and A ¹Σ⁺ electronic states of the LiH molecule, are calculated from threshold to 1000 eV by using the threshold-modified Massey–Mott approximation. The rate coefficients for the same transitions are also calculated in the range 0.1–1000 eV. Scaling relationships for both the v − v′ cross section and v − v′ rate coefficients are derived, allowing us to represent the calculated quantities in a compact analytic form. (paper)
