The excitation functions of the reactions V-51(n,alpha)Sc-48, Co-59(n,alpha
)Mn-56 and Co-59(n,p)Fe-59 have been measured by activation technique using
high resolution HPGetector gamma -ray spectroscopy. Monoenergetic neutrons
were produced via D-T reaction at J-25 neutron generator facility of the I
nstitute of Nuclear Science and Technology, AERE, Savar, Dhaka, Bangladesh.
Monitor Reaction Al-27(n,alpha)Na-24 was used to determine neutron flux at
different energy position in the range 13.57-14.71 MeV. The measured cross
section values along with the literature data have been plotted as a funct
ion of neutron energy to get the excitation functions of the reactions. Mod
el calculations using statistical code SINCROS-II was performed to validate
the experimental data theoretically.
