As far as I know these are the correct expressions, according to my professor.
For now, assuming these expressions are correct, this is what I have come up with (I could be on the wrong track though):
Set T=1. The numerator and denominator both have 2kq, so find cases in which cos=1 and...
So the standard deviation is sqrt(<p2>-<p>2), which equals p0/sqrt(12)?
My textbook says to put 2*pi*hbar (=h) in front of the integrals, I wasn't sure if that had something to do with me getting strange answers though.
Homework Statement
An electron with kinetic energy 5 eV (8.01E-19 J) passes through a 3 eV (4.806E-19 J) potential barrier. There are certain widths for this potential barrier in which the transmission probability will equal one hundred percent and the reflection probability will equal zero...
