Single-γ, γγ-coincidence and internal-conversion electron spectra of the 65Cu(α, nγ) 68Ga reaction were measured with Ge(HP) γ-ray and superconducting magnetic lens plus Si(Li) electron spectrometers at 14.5 MeV α-particle energy. The energies and relative intensities of 98 γ-transitions have been measured. Internal-conversion coefficients were determined for 19 transitions. A more complete level scheme with many new levels, γ-ray branching ratios, level spin and parity values have been deduced. The energy spectrum and electromagnetic moments were calculated on the basis of the interacting boson-fermion-fermion/truncated quadrupole phonon model for odd-odd nuclei (IBFFM/OTQM).
