The Radioactive Decay of Calcium 47

Abstract

Spectrometric studies have been made of the beta and gamma radiations from calcium 47 (5.35 day) and its radioactive daughter scandium 47 (3.4 day). Using conversion and photoelectrons and the scintillation spectrometer, gamma rays of energy 149.5, 234, 495, 800, and 1303 kev are found in scandium following beta emission from the calcium. The beta spectrum is complex with energies of 0.46 and 1.4 Mev.
