Formula for penetration coefficient in barrier penetration when ∪0-E is presented, and the question in the article 《The reserch on barrier of quantum mechanics from a piece of exercise》(《College Physics》 1993, 12(10)) is explained using this formula.

Using the method of the local transmission matrix, we generalize the well-known WKB formula for barrier penetrability to multichannel systems. We compare the WKB penetrability with a solution of the coupled-channels equations, and show that the WKB formula works well at energies well below the lowest adiabatic barrier. We also discuss the eigenchannel approach to a multichannel tunneling, which may improve the performance of the WKB formula near and above the barrier.
