For the arrangement of Figure (a) and Figure (b), electrons in the incident beam in region 1 have energy E = 836 eV and the potential step has a height of U1 = 627 eV. What is the angular wavenumber in (a) region 1 and (b) region 2? (c) What is the reflection coefficient? (d) If the incident beam sends 5.60 × 105 electrons against the potential step, approximately how many will be reflected?
