Abstract

The decay of Ba9015646 to levels of odd-odd La8915746 has been studied in experiments in which γγt coincidence, γγt(θ) angular correlation, γ-ray singles, and time-dependent γ-ray spectra were collected. The Ba146 activity was produced directly by on-line mass separation from the fission products of the U235(nth,f) reaction. The half-life of Ba146 was determined to be 2.22±0.07 sec. A level scheme containing 48 levels and 231 γ rays is proposed for La146. Spin and parity for some levels below 1.2 MeV are assigned on the basis of angular correlation measurements and β-ray branching. Details of the level scheme are discussed within the context of the level systematics of neighboring odd-odd La isotopes and N=89 odd-odd isotones.
