采用最小仪器展宽优化的单晶衍射仪测量了3d过渡金属Cr、Mn、Fe、Co、Ni和Cu的K α（1，2）和K β（1，3）发射光谱。高精度衍射仪和采用干涉校准的硅晶体确保绝对波长在公制尺度下达到百万分之一的精度。一个准确的分析表示的每条线，通过一个适合的最小集合的洛伦兹，提出。的绝对能量，线宽，和指数的不对称性，来自数据，同意与以前的测量。强度比K α（2）/K α（1）和K β（1，3）/K α（1，2）也是如此，然而，它们略微但一致地高于先前的值。所观察到的Z-依赖的趋势可能的起源进行了讨论。[S1050-2947（97）03012-6]。
The K alpha(1,2) and K beta(1,3) emission spectra of the 3d transition metals Cr, Mn, Fe, Co, Ni, and Cu were measured, employing a single-crystal diffractometer optimized for minimal instrumental broadening. The high-accuracy diffractometer, and the interferometrically calibrated silicon crystal employed ensure absolute wavelengths in the metric scale to a sub-part-per-million accuracy. An accurate analytic representation of each line, obtained by a fit to a minimal set of Lorentzians, is presented. The absolute energies, linewidths, and indices of asymmetry, derived from the data, agree well with previous measurements. So do also the intensity ratios K alpha(2)/K alpha(1) and K beta(1,3)/K alpha(1,2), which are, however, slightly, but consistently, higher than previous values. Possible origins for the observed Z-dependent trends are discussed. [S1050-2947(97)03012-6].
