XRF with a primary X-rays from the target with monoisotopical surface layer
The development is presented of X-Rays fluorescence analysis using as primary source proton induced X-Rays emission. It is offered to make primary target as double-layer using as the backing natural intermixture of isotopes, and as the upper layer - an isotope with the highest threshold of (p,n)-rea...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | The development is presented of X-Rays fluorescence analysis using as primary source proton induced X-Rays emission. It is offered to make primary target as double-layer using as the backing natural intermixture of isotopes, and as the upper layer - an isotope with the highest threshold of (p,n)-reaction for given element. Such target allows to reach lower detection limits by decreasing of background γ-emission from (p,n)-reactions. The making of target from copper, nickel, zirconium, and molybdenum are discussed. The presented approach has been used for elemental analysis of the samples of zirconium compounds and alloys, soils, plants and sediments. |
