Quantum Mechanics: WKB Approximation

out of 5 stars

09 Jul 2008 | | Contributor(s):: Dragica Vasileska, Gerhard Klimeck

In physics, the WKB (Wentzel–Kramers–Brillouin) approximation, also known as WKBJ (Wentzel–Kramers–Brillouin–Jeffreys) approximation, is the most familiar example of a semiclassical calculation in quantum mechanics in which the wavefunction is recast as an exponential function, semiclassically...
