Abstract

Because of the importance of knowing the values of these constants as accurately as possible, x-ray diffraction patterns were made for several samples differently treated as follows, (1) W plus 10 parts flour in comparison with NaCl in the other end of specimen tube; (2) the same in comparison with Au plus 10 parts flour, and (3) W plus 10 parts NaCl. The results agree within the reproducibility of the results,.001 to.003A, with the values previously obtained for lattice parameter ( $α = 3.155 \pm .001$ ) and density ( $D = 19.32 \pm .02$ ).
