Abstract:	New high-spin states were identified in the ²⁰⁵Tl isotope produced in deep-inelastic heavy-ion reactions. The expected 29/2⁺ yrast state and 35/2^- isomeric state with 235 ns half-life were located above the 2.6 s 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 ²⁰⁸Pb core with the three-hole structure of the 35/2^- isomer.Received: 20 January 2003, Revised: 10 March 2003, Published online: 2 March 2004PACS: 21.60.Cs Shell model - 23.20.Lv Gamma transitions and level energies - 27.80. + w - 25.70.Lm Strongly damped collisions
