The ~-radiation associated with the fl+ decay of ~3~ to levels in 13~ is studied. The level scheme is established on the basis of the Y-7 coincidence measurements emploing two Ge(Li) detectors. The available experimental data are compared to collective model calculations with V-soft P.E.S. and v-dependent inertial functions. To reproduce levels energy Bo~ value twice as large as other mass parameters is needed. Radioactivity: ~3~ [from ~3~Ep=10MeV]; measured E~, 17, ),y-coin. 13OBa deduced levels, J, re, log ft. Enriched target, Ge(Li) detectors.
