Thompson, B V

Baym's treatment of coherent scattering of slow neutrons by a crystal is examined and modified to include effects due to the cubic-anharmonic term in the lattice potential to second order in the coupling constant. Corrections to the Debye-Waller factor and to the onephonon'' resonance peak are obtained, which appear to be negligible ( approximately 0.01%) for the case of a Bravais lattice and certainly <1% in other cases.
