Abstract

The design and performance of a Siegbahn type double-focusing beta spectrometer of radius of curvature 50 cm. are described. It has a resolution of 0.3% with a transmission of a few tenths of a per cent. A study of the decay of In114 has revealed gamma rays in the K-capture branch of energies 0.556, 0.576, 0.722, 1.271, and 1.300 Mev. These define excited levels in Cd114 of energies 0.556, 1.278, and 1.856 Mev. above the ground state. The end point of the β spectrum is at 1.984 ± 004 Mev.
