(a) Suppose a beam of 5.0eV protons strikes a potential energy barrier of height 6.0eV and thickness 0.70 nm, at a rate equivalent to a current of 1000 A. How long would you have to wait-on average-for one proton to be transmitted?
(b) How long would you have to wait if the beam consisted of electrons rather than protons?
