Abstract: The structure of neutron-rich even-even 66-76Ni have been investigated by means of large-scale shell-model calculations. The energy levels for positive and negative parity states and the reduced transition probabilities B (E2; 02) are calculated by using the shell model code Nushellx by employing the effective interactions jun45 and jj44b. The results for excitation energies and reduced transition probabilities are compared with the recent available experimental data. Reasonable agreement is obtained for all isotopes under study.
