Activation cross sections of some neutron-induced reactions in the energy range of 13.82-14.71 MeV

The cross sections of the reactions Zn-70(n,2n)Zn-69m,Ge-74(n,alpha)Zn-71m and Zr-90(n,2n)Zr-89m,Zr-g in the energy range of 13.82-14.71 MeV were measured by the activation technique in combination with HPGe detector gamma-ray spectroscopy. The measured results were compared with other experimental data and with the data given in the library TENDL-2019. A nuclear model calculation based on the code TALYS-1.8 was also performed after adjustment of an input parameter for the spin distribution of level density. The results of this work strengthen the database and could be useful in further evaluation of the data.
