Large-scale shell model calculations for neutron-rich odd-A 63-73Ni isotopes have been performed
in the lower f5/2 pg9/2-shell region. The energy levels for positive and negative parity states up to
J=15/2 are calculated by using the shell model code Nushellx@msu by employing the effective
interactions jun 45 and jj44b. The theoretical calculations are compared with the most recent
available experimental data. Reasonable agreement is obtained between the theoretical values and
the experimental data for the selected isotopes under study.
