TRISTAN facility

The study of the 0 decay of 0.59s 145Cs was conducted at the TRISTAN mass separator on-line to the high flux reactor at BNL. A detailed description of the TRISTAN facility can be found in reference [GIL81]. The radioactive samples were produced by fissioning a uranium target integrated in a positive surface ionization source.[PI084] In this experiment, the usual Re surface ionizer was replaced with a Ta ionizer. The lower work function of Ta ensured no independent production of Ba from the ion source at a low power operation ( 1200°C). 

An Investigation of the 3 decay of the 0.59s 145Cs was made at the TRISTAN on-line mass separation facility. The level scheme for 145Ba has been constructed. The proposed spin and parity assignments are based upon transition multipolarities and yy angular correlation measurements.
