Description
Neutron structure factors of NH4Cl have been measured on a single crystal at 138 K by neutrons of 1.070 A wavelenght. Corrections for extinction and thermal diffuse scattering were estimated. Analysis of the nuclear motions was made by least-squares techniques using harmonic approximation for the vibrations and cubic harmonic expansion in treatment of librations of the NH4 ion including radial vibrations of the NH bond. Parameter values necessary for combination with an X-ray diffraction analysis are given. (author)
