AbstractAbstract
[en] Excited states up to Ex=2.0 MeV in 73 As have been investigated with the 73 Ge (p,nγ) reaction at incident energies of 3.15, 4.0 and 4.5 MeV. Lifetimes of twelve levels have been determined by Doppler Shift Attenuation method. A comprehensive analysis of the structure of 73 As has been performed within the IBFA model. Multi-shell calculations (1f7/2, 2p3/2, 1f5/2, 2p1/2, 1g9/2 and 2d5/2 proton orbitals coupled to a 72 Ge core) have been performed and compared to the existing experimental information: excitation energies, Jπ values, absolute electromagnetic transition probabilities, branching ratios and one-proton pickup and stripping spectroscopic factors. A reasonable agreement has been obtained for a large number of levels. A comparison of the experimental and calculated levels is given. (authors)
