Reactions <sup>64</sup>Zn( alpha ,p gamma )<sup>67</sup>Ga and <sup>53</sup>Cr(<sup>16</sup>O, pn gamma )<sup>67</sup>Ga populated the levels in <sup>67</sup>Ga. Gamma-gamma coincidence experiments were carried out at E<sub>alpha </sub>=13 and 15 MeV with the ( alpha ,p gamma ) reaction and E<sub>(16)O</sub>=42 MeV with the heavy-ion reaction. The Doppler-shift attenuation method was used with the ( alpha ,p gamma ) reaction to deduce mean lifetimes (or limits) for certain levels, along with the recoil-distance method utilised both in singles and gamma - gamma coincidence with the heavy-ion reaction. A mean lifetime of tau <sub>m</sub>=60+or-30 ns for the first excited state at 167 keV was measured using the delayed coincidence method. Gamma-ray angular distributions and linear polarisations were measured at E<sub>alpha </sub>=13.5 MeV using a Ge(Li)-NaI(Tl) escape-suppressed spectrometer and a three-Ge(Li) Compton polarimeter and analysis resulted in spin and parity assignments. Transition strengths were calculated and the results are discussed in terms of the particle-cluster-vibrational-core coupling model. |
