Coincidences corresponding to E-x approximate to 4.4-6.1 MeV have been used to constrain the shape of the nuclear level density and gamma-strength function of Ni-65 by means of the Oslo method. The experimental gamma-strength function presents an enhancement at. energies below E-gamma approximate to 3 MeV. In addition, a resonance-like structure centered at E-gamma approximate to 4.6MeV is seen together with accumulated strength at E-gamma approximate to 2.6-3.6MeV. The obtained results contribute to the systematic study of. decay in the Ni isotopes, which is of great interest for the understanding of both single-particle and collective nuclear structure phenomena.We are also grateful for the financial support received from the Research Council of Norway (NFR).
