Abstract : Radiations from the decay of 133Sb have been studied with use of solid state and scintillator gamma and beta detectors. Singles gamma, gamma-gamma, and beta-gamma measurements have been performed, and a decay scheme for 133Sb has been constructed consisting of levels at 0, 334, 979, 1152, 1679 and 2776 keV. Beta branches and log ft values have been deduced. The Q sub beta for 133Sb has been measured to be 3450 plus or minus 200 keV. The decay scheme is interpreted according to single-particle shell model and quasi-particle-phonon coupling theory. Some gamma rays have been attributed to 132Sb, principally one at 1024 keV which is probably the 2+ first excited level. (Author)
