“…The energy difference between these two lines is beyond the resolving power of the spectrometer employed, so that the intensities of these two lines had to be combined in the L fluorescence line intensity. For the sake of completeness, it is worthwhile to state that the other common notation for the fluorescence lines is the IUPAC notation [50]. For the L  fluorescence line, the IUPAC notation is L 3 M 5 , for the L  fluorescence line, L 3 M 4 .…”

The fluorescence yield of the K-and L3-shell of gallium was determined using the radiometrically calibrated (reference-free) X-ray fluorescence instrumentation at the BESSY II synchrotron radiation facility. Simultaneous transmission and fluorescence signals from GaSe foils were obtained, resulting in K-and L3-shell fluorescence yield values (ω Ga,K = 0.515 ± 0.019, ω Ga,L3 = 0.013 ± 0.001) consistent with existing database values. For the first time, these standard combined uncertainties are obtained from a properly constructed Uncertainty Budget. These K-shell fluorescence yield values support Bambynek's semi-empirical compilation from 1972: these and other measurements yield a combined recommended value of ω Ga,K = 0.514 ± 0.010. Using the measured fluorescence yields together with production yields from reference Ga-implanted samples where the quantity of implanted Ga was determined at 1.3% traceable accuracy by Rutherford backscattering spectrometry, the K-shell and L3-subshell photoionization cross sections at selected incident photon energies were also determined and compared critically with the standard databases.

The Cauchois and Sénémaud Tables are now available at the following address : http://www.lcpmr.upmc.fr/themes-A2f.php The definitive version of the paper is available at www3.interscience.wiley.com X-Ray Spectrom. 2011, 40, 12-16International audienceWe present the Cauchois and Sénémaud Tables of X-ray emission lines and absorption edges. They are written both in French and English. They were published in 1978 by Pergamon Press and are insufficiently known. However they are of large interest because of their completeness. They comprise the energies of all the K, L, M, N and O emission lines of natural elements from lithium up to uranium as well as the energies of satellite emissions and absorption discontinuities. The more intense lines of radio-elements up to fermium (Z = 100) are also given. The Tables range from the hard X-rays (122 keV, 0.01 nm) to the extreme ultra-violet (12 eV, 102 nm). For each transition, the wavelength (Å and uX) and energy (eV and Ry) are given and references are indicated. The transitions are grouped by increasing wavelength (decreasing photon energy) and also by element and spectral series. We present, as an example, the use of the Tables to identify the emissions of the molybdenum L spectrum. We decided to scan the Cauchois and Se ́ ne ́ maud Tables and make them available for the scientific community. They are now available at the Website of our laboratory, http://www.lcpmr.upmc.fr/

Internal conversion of low-energy nuclear transitions occurs with a high probability in heavy nuclei. After the emission of the conversion electron, a cascade of X-rays, Auger or Coster-Krönig electrons takes place. In α-decay experiments in which the nuclei of interest are implanted into a silicon detector, these atomic processes contribute to the detected energy. To understand the distortions of the alpha-particle energy spectra, knowledge of the various atomic yields is required. Using state-ofthe-art calculations, new atomic yields are computed in 99 Es and compared to those available in the literature. Detailed simulations of the 251 101 Md alpha decay are performed and compared to experimental data. Possible ways to discriminate between the available atomic yields are also discussed.
