Recent measurements of the temperature dependence of phonon energies in solid neon do not agree with the results of previous theoretical treatments. This discrepancy is remedied here with a calculation of the one-phonon Green's function by a perturbative method which includes the leading corrections to the lowest order self-consistent phonon theory. The renormalized phonon energy is then identified with the peak of the imaginary part of the Green's function. © 1969 The American Physical Society.
