Question

A 3.0 MeV proton is incident on a potential energy barrier
of thickness 10 fm and height 10 MeV.What are (a) the transmission
coefficient T, (b) the kinetic energy Kt the proton will have
on the other side of the barrier if it tunnels through the barrier,
and (c) the kinetic energy Kr it will have if it reflects from the
barrier? A 3.0 MeV deuteron (the same charge but twice the
mass as a proton) is incident on the same barrier.What are (d) T,
(e) Kt, and (f) Kr?
