Decay of /sup 142/Ba to levels of odd-odd /sup 142/La

; ; ; ; ; ; ; ; ;
The ..gamma..- and ..beta..-ray radiation following the decay of /sup 142/Ba to /sup 142/La were measured in experiments in which ..beta.. end-point energies, ..beta gamma.. coincidences, ..gamma..-ray singles, ..gamma gamma..t coincidence, and ..gamma gamma..t(theta) angular correlation data were collected. The /sup 142/Ba activity was produced by on-line mass separation from the /sup 235/U(n/sub th/,f) reaction. A level scheme for odd-odd /sup 142/La was deduced from coincidence information that includes 90 ..gamma.. rays which are placed among 23 levels. A 0.87 +- 0.17 ..mu..s isomeric state was established at 145 keV. The Q/sub ..beta../ value of 2200 +- 25 keV was determined from ..beta..-..gamma.. coincidence data. Beta-ray intensities and logft values have been evaluated, and along with internal conversion and angular correlation measurements, yielded spin-parity assignments for a number of levels. The low-lying levels were compared with level schemes projected from ..pi nu.. multiplet parabolas computed using parameters extracted from parabolic fits in /sup 140/La and /sup 142/Pr.
