Abstract

High spin states of doubly odd Fr127214 have been investigated using in-beam γ-ray and conversion electron spectroscopy techniques through the Pb206(11B, 3n) and Pb208(11B, 5n) fusion-evaporation reactions. Completely new spectrocopic information has been obtained. The yrast level structure is established up to spin (19+) and some information on γ transitions from higher-lying levels is also obtained. Two new isomers T1/2=174(20) ns and T1/2=11(2) ns were found. Configuration assignments for the low-lying levels are discussed. Information on residual proton-neutron interactions is extracted.
