5.) Tunneling Effect (14 pts.) In Rutherford scattering, a
proton of kinetic energy 10 MeV undergoes a head-on collision with
an uranium nucleus. Assume the nucleus to form a square electric
potential barrier of height 13 MeV and width 10 fm. (a) Calculate
the penetration depth of the proton (in fm). (b) Calculate the
transmission coefficient for the proton to reach into the uranium
nucleus (possibly inducing fission).

3. The process of alpha-radioactivity is an example of a barrier tunneling phenomenon, which can be envisioned as an alpha particle trapped inside a nucleus by a "Coulomb Barrier" produced by the combination of the attractive nuclear force that exists inside the nucleus, and the repulsive Coulomb force. A very crude picture of this situation is shown in the picture below, where we make the approximation that the alpha particle must tunnel through a square potential barrier to escape the...
