Beta decays of /sup 126/Cd and /sup 126/In to levels in /sup 126/In and /sup 126/Sn. [J,. pi. ]
A study of the beta decays of /sup 126/Cd and /sup 126/In using the TRISTAN on-line isotope separator facility is reported. Gamma-ray singles measurements were made for both decays usng Ge(Li) and LEPS (low energy photon spectrometer) detectors. In addition, gamma--gamma coincidence measurements and gamma multiscale measurements were made for both decays using Ge(Li) detectors. The half-life for /sup 126/Cd was determined to be 0.506 +- 0.015 sec., and the half-lives for the low- and high-spin /sup 126/In isomers were determined to be 1.83 +- 0.11 sec. and 1.96 +- 0.10 sec., respectively. A total of 11 gamma rays were observed in the decay of /sup 126/Cd, and all but one were placed in a level scheme for /sup 126/In. A total of 48 gamma rays were observed in the decay of the low- and high-spin /sup 126/In isomers and all were placed in a level scheme for /sup 126/Sn. Spin and parity assignments were deduced, whenever possible, on the basis of logft values and gamma decay selection rules. The /sup 126/In decay schemes (one has been proposed for each isomer) are compared with earlier decay studies and with results from /sup 124/Sn(t,p)/sup 126/Sn reaction experiments. The systematics associated with the level schemes are discussed and a comparison is made with the nuclear shell model. 49 references.
