Abstract

Excitation functions were measured for 70Ge(n,p)70Ga, 73Ge(n,p)73Ga, 74Ge(n,p)74gGa, 71Ga(n,p)71mZn, 71Ga(n,2n)70Ga, 67Zn(n,p)67Cu and 68Zn(n,a)65Ni reactions in the neutron energy range of 6.2 to 12.4 MeV. Quasimonoenergetic neutrons in this energy range were produced via the D-D reaction on a D2 gas target at the Jülich compact cyclotron (CV 28). Use was made of the activation technique in combination with high resolution HPGe-detector γ-ray spectrometry. In a few cases, radiochemical separations and low-level β- counting were applied. For most of the reactions, our measurements provide the first consistent sets of data near their thresholds. Nuclear model calculations using the code STAPRE, which employs the Hauser-Feshbach (statistical model) and exciton-model (precompound effects) formalisms, were undertaken to describe the excitation functions of all the investigated reactions. In most cases, the calculated values agree fairly well with the experimental results.
