Abstract

The Doppler-shift attenuation method (DSAM) has been used to measure the lifetime of 11 levels in 59Ni (4 were measured for the first time) and 2 in 57Ni. From these measurements, accurate excitation energies were determined for the levels below 2.8 MeV in 59Ni. A complete line-shape analysis has been performed on the basis of the description of the stopping process of the recoiling nuclei given by Warburton et al. The measurements were made using the 56Fe(α, nγ)59Ni and 54Fe(α, nγ)57Ni reactions at bombarding energies between 7.5 and 10.5 MeV for 59Ni and at 9 MeV for 57Ni. Enriched targets were used. The lifetimes of the states in 59Ni obtained with four different stopping materials (C, Fe, Cu, Au) were found to be consistent. The results are compared with recent shell model calculations.
