Abstract

Gamma rays from the decays of Sc50, Scm50, Ca50, and K47, produced by Ca48+t reactions at Et=3.2 MeV, were investigated with a Ge(Li) detector. A 3.5-MV Van de Graaff and a "rabbit" target-transfer system were used. Precision energy measurements resulted in the following γ-ray energies (in keV): Sc50, 523.792(18), 1121.124(5), and 1553.768(8); Ca50, 71.552(5), 256.894(10), 1519.300(20), and 1590.850(30). Relative γ-ray intensities were also measured and more accurate β and γ-ray branches in the decay schemes of Sc50, Ca50, and K47 were obtained. Limits were set on unobserved branches and, in Sc50 decay, five new β branches were found. By using a short timing cycle it was found that a possible β branch from Scm50 to the 2+ 1554-keV state of Ti50 is <2.5%. An incidental result was a value of 520.436(15) keV for the lowest energy γ ray in Rb83 decay. The β decay of Sc50 is compared to shell-model predictions.
