About this document
WKB Approximation in Quantum Mechanics by Marisol Hernández Sánchez is a document available to read on EtoBox.
The WKB approximation provides an analytical solution to the Schrödinger equation when the potential varies slowly. It assumes the wavefunction takes the form of e^iu(x), where u(x) is approximated iteratively. The first approximation yields the WKB wavefunction as the square root of the local wavenumber times an exponential. This approximation describes tunneling through barriers and is used to derive the alpha decay rate from a nuclear potential.
