High spin states in66,68Ge

High spin states of^66,68Ge have been investigated at the FN Tandem accelerator of the University of Köln via the reactions⁴⁰Ca(³²S,2p,4p)^66,68Ge at a beam energy of 100 MeV and⁵⁸Ni(¹⁶O,2p)⁶⁸Ge at 65 MeV. The OSIRIS spectrometer with 12 escape suppressed Ge detectors was used to measure coincidences and -ray angular distributions. In⁶⁶Ge (⁶⁸Ge) 33 (22) new levels were found and 63 (62) new -transitions were placed in the level scheme. Both nuclei show a rather complicated but similar excitation pattern, ruled by the interplay of quasiparticle and collective degrees of freedom. The results are compared to the recently published EXVAM calculations for⁶⁸Ge.Supported by German BMFT under contract No. 06 OK 143.
