Double Delta Function Scattering Potential
 The one-dimensional double delta function potential,  , is perhaps the simplest example of a scattering problem exhibiting the phenomenon of resonance. As the scattering wavefunctions can be found in closed form, it constitutes a very useful textbook-style example.The resonance can be thought of as arising from interference between paths that are reflected a different number of times between the two barriers. In this Demonstration, both the energy of the incoming particle and the spacing between the two barriers can be varied. Snapshot 1: lowest order resonance, corresponding to approximately half a wavelength between the two barriers   "Double Delta Function Scattering Potential" from The Wolfram Demonstrations Project http://demonstrations.wolfram.com/DoubleDeltaFunctionScatteringPotential/ Contributed by: Peter Falloon | ||||||||||||||
