Problem

Uranium-233 decays to thorium-229 by α decay, but the emissions have different energies and products: 83% emit an α particle with an energy of 4.816 MeV and give 229Th in its ground state; 15% emit an α particle of 4.773 MeV and give 229Th in excited state I; and 2% emit a lower energy α particle and give 229Th in the higher excited state II. Excited state II emits a γ ray of 0.060 MeV to reach excited state I. 

(a) Find the γ-ray energy and wavelength that would convert excited state I to the ground state.
