Abstract: | The dynamics of the IH + Br heavy-light + heavy system is treated using the Born-Oppenheimer-type separation between the light and the heavy nuclear motions. The hydrogenic wavefunctions, that describe the H-nucleus motion for clamped I and Br nuclei, provide the potential energy curves and couplings that govern the I-Br relative motion. The Hatom exchange cross sections in the reactive collision: IH(v= 0,j) + Br → I + HBr(v′,j′) are found to strongly depend upon j and to be large only for v′ = 1 with j′ = 16–20 and for v′ = 2 with j′ = 8–11. The present results are compared to our previous estimates, to results of classical trajectory calculations and to available experimental data. |
