Abstract
The cross-sections for the reactions Zn-64(n,2n)Zn-63, Ge-76(n,2n)Ge75m+g and Sc-45(n,2n)Sc-44m were measured in the energy range 13.82-14.71 MeV. The activation technique was used in combination with high resolution HPGe detector gamma-ray spectroscopy. Neutrons were produced via D-T reaction at J-25 neutron generator of the Institute of Nuclear Science and Technology, AERE, Dhaka, Bangladesh. The neutron flux at each energy was determined using monitor reaction Al-27(n,alpha)Na-24. The nuclear model calculations using the computer codes SINCROS-II and EXIFON were undertaken to describe the excitation functions of the investigated reactions.
