Preparation of Bismuth and Antimony Sources for Beta Spectroscopy

Abstract

spectrometer, operated at a 0.1% momentum resolution, the required sources need a light backing, a uniform distribution over a well defined area and a minimum weight of deposit. The present methods describe the preparation of such sources for 207Bi and 124Sb. A standard electroplating cell made of perspex was used in both cases. 5 sources of 207Bi and 10 of 124Sb have been prepared with these procedures, obtaining good yields and uniformity in all cases.
