| dc.description | Excited states in <sup>67</sup>Ge were studied using the reaction <sup>64</sup>Zn( alpha ,n gamma ). Excitation functions for the production of <sup>67</sup>Ge determined the Q value for this reaction to be -8993+or-5 keV. Neutron-gamma coincidences at E<sub>alpha </sub>=15 MeV and gamma - gamma coincidences at E<sub>alpha </sub>=13 and 15 MeV helped in the placing of 25 gamma rays into a decay scheme of 14 levels in <sup>67</sup>Ge. The first excited state was placed at 18.3 keV and the 734 keV gamma ray has been identified as a decay from a level at 751.8 keV to the 18.3 keV level. The mean lifetimes of the isomeric states at 18.3 keV ( tau <sub>m</sub>=21.0+or-0.3 mu s) and 751.8 keV ( tau <sub>m</sub>=160+or-2 ns) have been determined by pulsed-beam techniques, the decay of the 18.3 keV state being detected by X-ray detection. The mean lifetime of the level at 751.8 keV (J<sup>pi </sup>=<sup>9</sup>/<sub>2</sub><sup>+</sup>) and the angular distribution and linear polarisation measured for the 734 keV gamma ray have limited the spin of the level at 1803 keV to <sup>5</sup>/<sub>2</sub> with a proposed negative parity. |
