7a50.10 Barrier Penetration and Tunneling

PURPOSE: To show a Gaussian Wave Packet perform barrier penetration and tunneling.

DESCRIPTION: A software program animates the virtual image of an idealized Gaussian wave packet. The wave packet moves forward and crashes into a barrier or a well.  The height and width of the barrier or well can be changed.  The wave packet is seen to both reflect and transmit at the barrier.  The resulting transmitted and reflected coefficients of the wave packet are calulated using the schroedinger wave equation.

EQUIPMENT: Computer and projector.

SETUP TIME: None.
