The spacing of the surface planes of a crystal is 159 pm. A beam directed normally at the surface of the crystal undergoes first order diffraction at an angle of 58 from the normal. The diffraction is done with a beam of monoenergetic neutrons.
 
  The energy of the neutrons is closest to: A) 0.045 eV
  B) 0.039 eV
  C) 0.050 eV
  D) 0.056 eV
  E) 0.061 eV
