An electron with kinetic energy E = 3.20 eV is incident on a barrier of width L = 0.110 nm and height U = 10.0 eV.
(a) What is the probability that the electron tunnels through the barrier? (Use 9.11 *10-31 kg for the mass of an electron, 1.055 *10-34 J · s for , and note that there are 1.60 *10-19 J per eV.)
(b) What is the probability that the electron is reflected?
