A Sanity Check on the WKB Method

I will talk about a little problem I did a long time ago when I was a grad student. It was to check whether the WKB method gives an answer as bad as having a factor of two error in solving for the tunneling probability over a potential barrier using the 1D Schrödinger equation, as claimed by a paper at that time. I ended up showing that the WKB method can get quite accurate answers over the whole range of energy, covering different regimes that require different treatments.
