Abstract
The nuclear-resonance photon-scattering cross section s from N15 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 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.
