Abstract
From (p, xn) in-beamγ-ray and electron measurements aT 1/2=235(14) ns isomer at 720 keV was identified in 14863 Eu85 and the levels populated in its decay have been characterized. The results determineI π=9+ for the isomeric state, and we assign it as the (πh 11/2 j −20 ν f 2/37 )9+ shell model state, analogous to the configuration of the 235 μs isomer in 14663 Eu83.

We thank J. Styczen, A. Ercan and R. Pengo for their help in the measurements at Jülich. P. Wieder provided skillful technical assistance at the in-beam experiments, and we received invaluable programming help from M. Karnadi for the data analysis. We gratefully acknowledge fruitful discussions with O. Schult and J. Blomqvist. One of us (A. P.) is thankful to the Academy of Finland for a grant.
