Precise X-ray measurements that map tungsten’s spectral lines

This scholarly report presents accurate wave-length measurements and spectral maps for tungsten’s L and K radiation. It explains how limiting crystal thickness and source width, and maximizing crystal-to-plate distance, sharpen line separation and enable reliable results. The work details the experimental setup, calibration methods, and how careful procedures yield consistent measurements over long exposures.

The author shows how the L group unravels into at least 19 distinct lines with measurements precise to a fraction of a percent. It also demonstrates that the tungsten K lines can be clearly separated in the first order when high resolving power is achieved. The findings compare favorably with prior work and include practical notes on apparatus operation and measurement accuracy.

• Step-by-step description of the experimental approach for L and K radiations
• Discussion of resolving power and its impact on line identification
• Tables and comparisons that situate Dershem’s measurements among contemporaries
• Technical details on apparatus, calibration, and data interpretation

Ideal for readers of early X-ray research and historians of physics seeking clear, methodical reporting of spectral measurements.
