Comparison between blackbody radiation and continuous X-ray spectra produced by electron deceleration

Abstract

The continuous X-ray spectral profiles are compared with the Planck's distribution law for blackbody radiation. The energy distributions of continuum X-rays produced by bombardments of 20 and 30 kV electron beams onto iron target are crudely reproduced by the blackbody radiation at about 10 7 K temperature at their absolute intensity scale.
