X-RAY DIFFRACTION STUDIES OF THERMAL MOTIONS IN CRYSTALS.
GEORGIA INST OF TECH ATLANTA ENGINEERING EXPERIMENT STATION
The quarterly progress report contains an abstract for a paper on Lattice Vibrations in AgCl and the Temperature Dependences of X-ray Bragg Intensities, by R. M. Nicklow and R. A. Young, to be presented at the Pittsburgh Diffraction Conference, November 1964. Also included is a foreword to the forthcoming Technical Report No. 3 that is essentially the Ph.D. thesis of Dr. R. M. Nicklow. TEMPERATURE DEPENDENCE OF BRAGG INTENSITY FOR PERFECT CRYSTALS IN BRAGG GEOMETRY Experiments are under way for measuring the integrated intensity as a function of temperature 100 to 400K and of the absolute value for g with crystals as free as possible of all defects and strains, where g is a zero parameter of an ideally perfect, nonabsorbing crystal according to Parthasarathy Acta Cryst. 13802-806 1960.
