Theoretical Continuous X-Ray Energy and Polarization

摘要: By the theory of Sommerfeld, relativity effects and retardation potential being neglected, matrix elements associated components continuous spectrum x-radiation are computed for a variety electron-nucleus collisions distributed series positions in spectrum. The calculations cover values $\frac{V}{{Z}^{2}}$ from 0.06128 to 3.356, where $Z$ is atomic number nucleus, $V$ bombardment electrostatic units. Accuracy calculation 1 percent. Screening neglected except at long wave limit spectra it taken into account by Sauter's method. Empirical algebraic formulas found which closely represent rigorously calculated results. Intensity polarization predictions any direction emission excitation conditions within range applicability may be readily drawn Elwert's proposed correction factor rectifying approximate spectral intensities Sommerfeld Maue effective limits its restricting assumptions. Theoretical efficiencies x-ray production combining theoretical with known rates electron energy loss traversing matter. Thick target efficiency (a ratio, not percent) given $1.4\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}6}Z$ kv. Thin approximately twice thick
