| Abstract: | Mean lives and excitation energies of the lowest levels in64Ni,66Zn and68Zn were measured with the aid of the (α, α′γ) and (α, pγ) reactions. The γ-rays were detected in coincidence with the outgoing particles. The following mean lives were determined from DSA measurements: 400 ± 150 fs for the level at Ex = 1.35 MeV in 64Ni; 270 ± 100, 210 ± 110, 330 ± 200, 80 ± 70 fs for the levels at Ex = 1.87, 2.45, 2.83, 2.94 MeV in 66Zn, and 1300 ± 300, > 160, 600 ± 200 fs for the levels at Ex = 1.08, 1.89 and 2.76 MeV in 68Zn, respectively. |
