A proton (mass m = 1.673 x 10-27 kg) is bound in a finite square well of width 4fm. The depth of the well is six times the ground-level energy of the corresponding infinite depths well.
a) What is the wavelength of a photon that can be absorbed to excite the nucleus?
b) What is the minimum energy of a photon to liberate the proton from the ground state?
