Abstract

The nuclear-resonance photon-scattering cross section s from ¹⁵N in the form of gaseous, liquid, and solid NH₃ was studied as a function of temperature in the range 15-600 K. The value of σ_s was found to be in excellent agreement with that calculated using an effective temperature of the N atom in which the internal vibrations of NH₃ and the external vibrations of the lattice were taken into account. The Debye temperature of NH3, as determined from the motion of the N atom only, was found to be FTHETA=241± 8 K.
