Abstract
New high-spin states were identified in the (TI)-T-205 isotope produced in deep-inelastic heavy-ion reactions. The expected 29/2(+) yrast state and 35/2(-) isomeric state with 235 us half-life were located above the 2.6 mus isomer known from previous studies. Above this isomer a 7092 keV level was interpreted as a 41/2(+) state arising from the coupling of the octupole vibration of the Pb-208 core with the three-hole structure of the 35/2(-) isomer.File in questo prodotto:
