SPECTROSCOPY OF PO-194

Prompt, in-beam gamma rays following the reaction Yb-170 + 142 MeV Si- 28 were measured at the ATLAS facility using 10 Compton-suppressed Ge detectors and the Fragment Mass Analyzer. Transitions in Po-194 were i dentified and placed using gamma-ray singles and coincidence data gate d on the mass of the evaporation residues. A level spectrum up to J ap proximate to 10 (h) over bar was established. The structure of Po-194 is more collective than that observed in the heavier polonium isotopes and indicates that the structure has started to evolve toward the mor e collective nature expected for deformed nuclei.
