Work on X-Ray Spectroscopy

A few years after the discovery of X-rays, Charles Barkla showed that compounds exposed to X-rays emitted secondary X-rays with wavelengths that were characteristic of different elements. After studying a number of elements, Henry Moseley was able to add to and revise the periodic table. Manne Siegbahn developed apparatus and methods for improving accuracy when mapping x-ray spectra. This advance proved important in the development of atomic and quantum physics.
