晶格常数a在0.1%(.对于铝、铁、镍、铜、钼、钯、银、钨、铂、金、铅和铋，通过与氯化钠直接比较，a(氯化钠)=2.814 A)。使用所能获得的纯样品，从镍的99.55%到钨的99.9995%，在许多情况下还测量了商业上的纯样品进行比较。最纯样品的结果汇总于表十三。从X射线数据得到的密度(Al和Ag除外)都大于文献中给出的块体金属的密度，其中Mo(10.21vs9.1)、Pd(12.25vs11.9)和W(19.32vs18.77)的差异相当大。对于纯W，获得了非常清晰的谱线。对于铋，使用了一块单一的人造晶体。
The lattice constant a has been determined within 0.1 percent (. 03 percent for W) for aluminum, iron, nickel, copper, molybdenum, palladium, silver, tungsten, platinum, gold, lead and bismuth, by direct comparison with NaCl, a (NaCl)= 2.814 A. As pure samples as could be obtained were used, from 99.55 percent for Ni to 99.9995 percent for tungsten, and in many cases commercially pure samples were also measured for comparison. The results for the purest samples are summarized in Table XIII. The density from the x-ray data is in each case (except Al and Ag) greater than the density of the bulk metal as given in the literature, the difference being rather large for Mo (10.21 vs 9.1), for Pd (12.25 vs 11.9) and W (19.32 vs 18.77). For pure W remarkably sharp lines were obtained. For Bi a piece of a single artificial crystal was used.
