Abstract: | The (18O, 20Ne) reaction on the even Ni isotopes has been studied at 63.0 MeV with ΔE-E time-of-flight telescopes. From the measured ground-state Q-value for the 64Ni(18O, 20Ne)62Fe reaction, ?1.97±0.20 MeV, a mass excess ?58.87±0.20 MeV is obtained for the 62Fe nucleus. This result is in good agreement with a recent measurement of the β-endpoint energy. Angular distributions for the transitions to the Fe ground states, leaving 20Ne in its ground and 1.63 MeV 2+ excited state, yield relative spectroscopic strengths in fair agreement with DWBA calculations based on simple shell-model estimates. |
