摘要：

A generalized WKB method for calculating transmission coefficients, for a general double barrier and for any energy of the incident particle, is developed. The conditions for resonance in the transmission coefficient are given. The theory is applied to a specific example and the results are compared to exact ones obtained by solving the Schrödinger equation numerically. © 1969.
