Abstract : 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. 13:802-806 (1960)).
