Abstract

An intermediate image magnetic spectrometer was used to study the continuousβ +-spectrum of Pr140 and the Auger electrons of the decay chain Nd140→Pr140→Ce140. The maximum energy of the continuous β+-spectrum is 2318±10 keV. The ratio of the intensities of the different Auger groupsK−LL∶K−LX∶K−MX=1 ∶ (0.58±0.05) ∶ ∶ (0.09±0.02). The ratio of the number of Auger electrons of the K-series to the electrons of the continuous spectrume K/β + is 0.292.
