Abstract

A first level scheme of $^{68} Se$ with five states up to 4.2 MeV excitation energy and tentative spins $6^{+}$ and $7^{-}$ has been established from γγγ coincidences measured with six EUROBALL Cluster detectors in close geometry. The level scheme is interpreted in comparison with neutron deficient nuclei of the $A \approx 70$ region and cranking model calculations. In a similar experiment a triple coincidence between the $^{72} Kr$ transitions 710, 611, and 792 keV has been proven.
