“…However, to the best knowledge of the present authors, no quantitative data have been published. This finding is in general agreement with most of the previous measurements and may be qualitatively explained (Siegbahn, 1925) by the fact that the highest-energy photons are only emitted from the surface of a thick target, while low-energy photons are also emitted from the internal part of a target where the electrons are deflected from the original path as they traverse the material of the target.…”

“…It is well known that in the case of a thin target the white radiation is strongly polarized in the direction parallel to the electron beam incident on the target (Kuckuck & Ebert, 1973;Tseng & Pratt, 1973;and references therein). Our knowledge of polarization in the case of thick targets stems mainly from early measurements (Siegbahn, 1925;Ross, 1928;and references therein). Recently, Slivinsky (1971) measured the polarization of X-radiation emitted by commercial X-ray tubes with thick targets and found that it is strongly polarized in the direction parallel to the electron beam at the high-energy limit of the Bremsstrahlung spectrum, while the lower-energy X-rays exhibit a low but constant polarization in the same direction.…”

Polarization measurements of the primary X-ray beam produced by thick copper and tungsten anodes are reported and formulas derived for integrated intensities of Bragg reflections in energy-dispersive diffractometry with the polarization of the primary beam taken into account. It was found that for an angle of 45° between the scattering plane and the plane containing the electron beam and the primary beam, the influence of polarization vanishes, while it increases as the angle changes from 45 ° to either 0 or 90 °. For the latter values, the influence of polarization is considerable at high photon energies and at scattering angles close to 90 ° .

This paper describes a few episodes from the early days of X‐ray spectroscopy. It relies on contemporary publications, especially those by Barkla, Moseley, Siegbahn, and Compton. The paper addresses the subject from the vantage point of physics and should be of interest to the X‐ray spectroscopist, who wants to obtain a glimpse of the history of his chosen field.

“…When high-energy electrons of the order of a few tens of keV kinetic energy bombard a metal target in an Xray tube, the continuous X-ray spectrum (Kuhlenkampff, 1926;Siegbahn, 1925;Stephenson, 1957;Panofsky and Phillips, 1961;Heitler, 1984;Landau and Lifshitz, 1951;Dyson, 1990;Haug and Nakel, 2004), or continuum X-rays, are generated due to the deceleration of electrons (Bremsstrahlung). Kramers (1923) assumed a parabolic path of incident electrons in the Coulomb field of nucleus (electron velocity vector is normal to the deceleration vector), and obtained an energy distribution of continuous X-ray emission spectra as…”
