Abstract
Low-spin states of have been populated by a fusion evaporation reaction followed by -decay . Two candidates for -states could be found, by measuring the mixing ratio of the transitions of the and , at 2150 keV and 2296 keV, to the first excited state. The experimental results are supported by a shell model calculation and are in a good agreement with interacting boson model-2 (IBM-2) calculations. The mixing of the with a symmetric -state and its fragmentation into the and states are discussed.
