Suppose a beam of 5.0 eV protons strikes a potential energy barrier of height 6.0 eV and thickness 0.58 nanometer, at a rate equivalent to a current of 805 A.
(a) Determine how long would you have to wait-on average-for one proton to be transmitted?
s
(b) Determine how long would you have to wait if the beam consisted of electrons rather than protons?
s
