PARTIAL CROSS-SECTIONS FOR THE GA-71(P,N-GAMMA) REACTION AND THE STRUCTURE OF THE LEVELS OF GE-71

The structure of the levels of Ge-71 up to the excitation energy 1.7 M eV is studied in the Ga-71(p,ngamma) reaction at incident-proton energ ies from 1.5 to 3.1 MeV. The cross sections for the (p,n) reaction cor responding to single states of the final nucleus are determined from t he yield of gamma rays. The results are compared with the cross sectio ns calculated according to the statistical theory, and the spins and p arities of the excited states of Ge-71 are determined. Calculations in the dynamical collective model give a satisfactory description of the experimentally determined properties of the levels of Ge-71.
