X-ray spectroscopy is an analytical technique that uses X-rays to study the composition of materials. It measures the energies and intensities of X-rays emitted or absorbed by a sample, providing information about the elements present and their chemical states.
In a major step forward, SLAC’s X-ray laser captures all four stable states of the process that produces the oxygen we breathe, as well as fleeting steps in between. The work opens doors to understanding the past and creating a...
