Question:

For the arrangement of Figs. 38-14, electrons in the incident beam in region 1 have energy E 800 eV and the potential step has a height of U1 = 600 eV. What is the angular wave number in
(a) Region 1
(b) Region 2?
(c) What is the reflection coefficient?
(d) If the incident beam sends 5.00 x 105 electrons against the potential step, approximately how many will be reflected?
