A proton (mass m = 1.673 E-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 proton 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?
