Energy dependence of the isotopic effect in the (n,p) reaction on the germanium isotopes

  • Published:
Zeitschrift für Physik A Hadrons and Nuclei

Abstract

Cross sections for70,72,73,74Ge(n, p)70,72,73,74Ga,70Ge(n, 2n)69Ge,72Ge (n,α)69Znm and74Ge(n, α)71Znm reactions are measured in the energy range from 13.0 to 16.6 MeV by the activation method using Ge(Li) detectorγ-ray spectroscopy and compared with predictions of the reaction model incorporating preequilibrium and equilibrium emission mechanisms to interpret the energy dependence of the isotopic effect occuring in the (n, p) reaction. The fitted single-particle state-density parametersg, determined here for the germaniums are discussed together with theg-values found previously for the Se, Zr and Pd isotopic chains. A validity of the consistency condition between the precompound and compound models, which relatesg to the experimental level-density parametera viaa=π 2 g/6 is demonstrated.
