On the effect of increasing the total angular momentum on Li+HF reactivity

The effect of increasing the total angular momentum J on the value of the reaction probability has been investigated theoretically using exact quantum calculations. The contribution of higher J probabilities to the calculated value of the cross-section has been treated as a correction to its J-shifting model formulation. Two interesting features of the calculated cross-section have been evidenced in this way: (a) as more exact quantum contributions are added to the calculation, the agreement between theory and experiment improves; (b) the resonance structure characterizing low-energy probabilities survives the averaging over partial waves.
