On X-Ray Satellites, Relative Intensities and Line Widths

Preliminary data are reported on the $L{\alpha }_{1, 2, 3, 4, 5, 6, 7}$ lines for Ag(47) and on the $M\alpha ,\beta$ lines for Au(79) recorded with a two-crystal spectrometer. But the primary purpose of this note is to indicate some of the difficulties in interpreting these and similar data. The disagreement between the present and earlier interpretations and results is large: a factor of about 2.5 in widths of $M$ series lines, a factor or about 2 in $\frac{{\alpha }_2}{{\alpha }_1}$ relative intensities, and a factor of about 4 in the satellite relative intensities. These discrepancies are due to differences in (1) the effective resolving power of the instruments used and in (2) the assumed shapes of the component lines comprising an unresolved complex structure.
