Abstract

Low-spin levels in

^{109} Sb

populated by

^{109} Te

beta decay are reported for the first time. Seven new levels are proposed, two below 1 MeV excitation energy. Spins and parities of

{(1 / 2}^{+})

and

{(3 / 2}^{+} {, 5 / 2}^{+})

are suggested for the low energy levels by comparison to beta feeding intensities and systematics. These results are compared with new calculated levels for

^{109} Sb .
