| The dynamics and kinetics of the H++ LiH reaction have been studied using a quantum reactive time-dependent wave packet (TDWP) coupled-channel quantum mechanical method on an ab initio potential energy surface at conditions of the early universe. The total reaction probabilities for the H++ LiH (v= 0, j= 0)→ H+ 2+ Li process have been calculated from 5× 10− 3 eV up to 1 eV for total angular momenta J from 0 to 110. Using a Langevin model, integral cross sections have been calculated in that range of collision energies and extrapolated for energies below 5× 10− 3 eV. The calculated rate constants are found to be nearly independent of temperature in the 10–1000 K interval with a value of≈ 10− 9 cm 3 s− 1, which is in good agreement with estimates used in evolutionary models of the early universe lithium chemistry. |
