新的X射线波长（能量）和宽度测量报告的一些元素从47\ensuremath {\le}Z\ensuremath{\le}92$。X射线是用电子货车德格拉夫产生的，测量是用一个配备有角度测量干涉仪的双轴平面晶体透射光谱仪进行的。这里报告的新测量结果，加上其他高精度的X射线波长，形成了一个适度广泛的数据库，与理论计算进行比较。与最近修订的一个以前可用的所有Z$计算的比较，揭示了改进的模式的一般协议，但是，重要的例外。新测得的线宽与通过相对论波函数计算的宽度一致，用于长期估计。
New x-ray wavelength (energy) and width measurements are reported for a number of elements from $47\ensuremath{\le}Z\ensuremath{\le}92$. The x rays were produced with the use of an electron Van de Graaff, and the measurements were made with a two-axis flat-crystal transmission spectrometer equipped with angle-measuring interferometers. The new measurements reported here, combined with other high-precision x-ray wavelengths, form a moderately extensive data base for comparison with theoretical calculations. Comparison with recent revisions of a previously available all-$Z$ calculation reveals improved patterns of general agreement with, however, important exceptions. The newly measured linewidths are in agreement with widths calculated via relativistic wave functions used for the term estimates.
