Abstract

γ-ray, γγ-coincidence, and internal conversion electron spectra were measured with Ge(HP), as well as superconducting and traditional magnetic lens plus Si(Li) electron spectrometers at different bombarding proton energies between 6.5 and 7.1 MeV. Energies and relative intensities of 131 (among them 52 new) 66Ga γ-rays have been determined. Internal conversion coefficients of 33 transitions were measured for the first time. A more complete level scheme with new levels, γ-ray branching ratios, level spin and parity values has been deduced. The energy spectrum and electromagnetic properties were calculated on the basis of an interacting boson-fermion-fermion/truncated quadrupole phonon model for odd-odd nuclei. The model calculations reasonably describe the level spectra and electromagnetic properties of 64Zn, 65Ga, 65Zn and 66Ga nuclei with consistent parametrization.
