Adiabatic wavepacket dynamics study of the N + NH → N2 + H reaction on the ground-state potential energy surface

The figure shows the integral cross section obtained from J = 0 shifting and some comparisons. It is a well known method to estimate integral cross sections via J-shifting type methodologies for barrierless reactions occurring over deep wells from only the J =0 reaction probability or just from a few individual J reaction probabilities.
