description

From (p, xn) in-beamγ-ray and electron measurements aT1/2=235(14) ns isomer at 720 keV was identified in63148Eu85 and the levels populated in its decay have been characterized. The results determineIπ=9+ for the isomeric state, and we assign it as the (πh11/2j0−2ν f72/3)9+ shell model state, analogous to the configuration of the 235 μs isomer in63146Eu83.
