| 英文摘要 | The level structure of Po-196 has been studied using a Dy-160 (Ar-40, 4n) reaction and a recoil-catcher technique to reduce fission. The results showed a sharp drop off in the first (2+) and (4+) energies relative to systematics implying an abrupt increase in the quadrupole collectivity at N = 112. In addition, second (2+) and (4+) states were identified at 859 and 1388 keV, respectively, suggesting the discovery of a 4p2h deformed band in Po isotopes which is related to known 2p2h proton bands in several Pb isotopes. A prompt W-183 (Ne-20, 5n) experiment located similar second 2+ and 4+ states at 1039 and 1483 keV in Po-198 providing corroboration and extended information on the properties of the new Po deformed bands. A measured halflife of 850 (90) ns for the 2491 keV (11-) state in Po-196 implied collective E3 contributions to the extracted B (E3; 11- --> 8+) = 27(5) W.u.. |
