The phenomenon is widely used for elemental analysis How does XRF work When high energy photons xrays or gammarays are absorbed by atoms inner shell electrons are ejected from the atom becoming photoelectrons This leaves the atom in an excited state The Xray absorbing gas is often called a warm absorber because UV observations show that it is accompanied by very weak or no signi64257cant absorption at the H I Lyman limit 912 A The gas must be substantially ionized much more H II than H I and he Blackburn PhD The xray image intensifier converts the transmitted x rays into a brightened visible light image Within an image intensifier the input phosphor converts the xray photons to light photons which are then converted to photoelectrons withi In this chapter we deal with the experimental arrangement as a whole There are general aspects to consider in settingup an xray experiment The sample is illuminated by an incident beam striking the sample surface under a de64257nite angle of inciden Visible light for example can be diffracted by a grating that contains scribed lines spaced only a few thousand angstroms apart about the wavelength of visible light Xrays have wavelengths on the order of angstroms in the range of typical interatomi B TBNNaNT AND R W BnnGBn Assrracr An rray method has been developed for the determination of the percentage of dolomite in a carbonate rock Such analyses may be useful in exploration work due to the association of highly dolomitized zones with locat By Cade Grigsby. 1.
