Near-contact adiabatic suppression of electron transfer in the inverted region

These changes affect significantly the spatial dependence of the transfer rate near the contact provided the coupling there is strong. The rate tends to zero at contact distance being strongly suppressed nearby adiabatically. It is much smaller then the perturbation (golden rule) and even DSE results. The latter is actually unattainable anywhere if contact tunneling is really strong. The transfer rate is a bell-shaped curve adiabatic and non-adiabatic on the opposite sides and sensitive to the friction (DSE damping) only in between, near the maximum.
