Erratum to: Analytical investigation of energy spectrums of beta rays emitted from 90Sr and 204Tl radioisotopes

Abstract

The energy spectra of beta rays emitted from 90Sr and 204Tl radioisotopes were obtained by using a silicon surface barrier detector with a 1000 μm depleted layer and 50 mm2 effective area. The detector response function is interpreted by making use of range distributions of mono-energetic electrons in matter and by assuming a linear energy loss along the range in the depleted layer of the detector. An analytical expression is given for pulse height distribution obtained in the surface barrier detector. A good agreement is observed between the experimental results and theoretical interpretation.
