Nonreactive scattering of the O+Â +Â H2: A time dependent wave packet approach

► We use TD wave packet method to calculate nonreactive O+ − H2 scattering probabilities. ► TID quantum close-coupling reaction probabilities for J = 0-30 are also calculated. ► Initial-state selected cross sections are obtained in the range of Ecol = 0.08-0.7 eV. ► We determined k(T) rate constants for nonreactive collisions of O+ + H2 up to 1000 K.
