let's say..(adsbygoogle = window.adsbygoogle || []).push({});

there is a particle, with mass m, in a 2-dimensions x-y plane. in a region

0 < x < 3L ; 0 < y < 2L

how to calculate the energy eigenvalues and eigenfunctions of the particle?

thx

and.. 2nd question..

there is a particle of kinetic energy E is incident from the left on the potential barrier, height U, situated at the origin. The barrier is infinitely wide and E>U.

how to get an expression for the reflection coefficient R of the particle, as a function of the ratio ε= E/U

and how would the sketch look like?

i dont really know how to work them out...
