Validity of the WKB Tunneling Probability Expression for Proton Transfer

Degree of Validity of the WKB Tunneling Probability Expression for Proton Transfer 

The question of the degree of validity of the WKB method was examined by Sen and Bockris.  

There is a solution to the tunneling problem provided by these wave functions. It gives for the transition probability, Pt, 

The following wave functions for the electron were chosen  

Using the time-dependent part of the wave function and taking the linear combination, one gets
