X-Ray Fluorescence Yields, Auger, and Coster-Kronig Transition Probabilities
, 1972The present status of the field of fluorescence yields, radiationless (Auger and Coster-Kronig) and radiative transition probabilities is summarized. Tables of experimental and theoretical results are included, and tables of "best values" of important ...

Radiation Dose Limits for Bioanalytical X-ray Fluorescence Microscopy.
Analytical Chemistry, 2017Analytical approaches that preserve the endogenous state of the examined system are essential for the in vivo study of bioinorganics. X-ray fluorescence microscopy of biological samples can map elements in vivo at subcellular resolutions in tissue ...

Review of Scientific Instruments, 2017
As X-ray fluorescence radiation isotropically spreads from the sample, one of the most important requirements for spectrometers for many years has been a large solid angle. Charge-coupled device (CCD) cameras are quite promising options because they have
