' A proton is trapped inside an infinite 3D square well with side length 1014m (an approximate size for some atomic nuclei) & Its mass m, = 1.67 x 10-27 kg. a) You observe a photon of wavelength 1.009 x 10-13 m emitted by the proton, which ends up in the ground state of the well. Which excited state did the proton fall from? Give its energy and give one possible set of quantum numbers for that energy. b) What is the degeneracy of the state you found in a)? if you did not nd a state for a), choose an excited state and give its degeneracy.|
