SINCE Moseley's discovery of the fundamental laws of the X-ray emission ... conclusive characteristic of a Chemical element is given by its X-ray spectrum. In addition, Moseley's laws allow ...

This causes line emission spectra to be produced ... produces photons with different energy and so the line spectra for different elements will be different. This means that line spectra can ...

The first, somewhat furtive, signal from element 63 was recorded in 1885 by Sir William Crookes, who found an anomalous red line (609 nm) in the emission spectrum of a samarium sample.

Optical Emission Spectroscopy ... offset element in the sample. The computer system acquires the measured strengths and processes this information using a predetermined calibration to output elemental ...
