Abstract
By extending the Miller-Good modified WKB approximation to include the higher-order terms, as derived by Lu and Measure, we are able to calculate the transmission coefficients for energies above the potential barrier. We show that the higher-order terms are essential to the approximation, especially for energies near the barrier top.Keywords
