  title = {Resonance electronic Raman scattering in Erbium phosphate crystals},
  abstract = {<p>Resonance enhancement factors of 10 to 100 have been observed for the electronic Raman scattering transitions in crystals of pure ErPO<sub>4</sub> and 1% Er<sup>3+</sup> diluted in LuPO<sub>4</sub>. The resonances were excited by the 488.0-nm line of an argon-ion laser. This line is nearly coincident with the crystal-field levels of the <sup>4</sup><em>F<sub>7/2</sub></em> multiplet of Er<sup>3+</sup>. The differences in relative intensities between the transitions in ErPO<sub>4</sub> and those in 1% Er<sup>3+</sup> in LuPO<sub>4</sub> arise from shifts in the energy levels in the two systems and suggest that quantum-mechanical interference effects play an important role.</p>},
