Systematic experimental and theoretical investigations of the 72,73Ge(n,p)72,73 Ga and 72,74Ge(n,α)69,71Znm reaction cross sections are presented in the energy range from thresh- old to about 17 MeV neutron energy. The above reaction cross sections were measured from 8.8 to 11.4 MeV by using the activation method, relative to the 27Al(n,α)24Na refer- ence reaction. The quasi-monoenergetic neutron beams were produced via the 2H(d,n)3He reaction at the 5 MV VdG Tandem T11/25 accelerator of NCSR “Demokritos”. Statisti- cal model calculations using the code EMPIRE-II (version 2.19) taking into consideration pre-equilibrium emission were performed on the data measured in this work as well as on data reported in literature.

Excitation curves for the reactions Fe56(n, p)Mn56 and Co59(n, α)Mn56 have been measured by the activation method from near threshold energies to 20.3 Mev. The measurements are relative to the known cross section for the S32(n, p)P32 reaction. Cross sections for both reactions increase smoothly with neutron energy and reach maximum values of 119 ± 4 mb for the Fe56(n, p) reaction at 13.6 Mev and 30.0 ± 0.9 mb for the Co59(n, α) reaction at 14.5 Mev. Above 15 Mev both cross sections decrease with neutron energy. From the excitation curves effective cross-section values for a fission-neutron spectrum have been calculated as 1.04 ± 0.05 mb for the (n, p) reaction and 0.140 ± 0.007 mb for the (n, α) reaction.

Cross-sections of the reactions 79 Br (n, 2n)78 Br , 63 Cu (n,2n)62 Cu , 58 Ni (n, 2n)57 Ni , 54 Fe (n, 2n)53 Fe , 50Cr(n, 2n)49Cr and 46 Ti (n, 2n)45 Ti induced by 14.7 MeV neutrons are measured with reference to 27Al(n, ∝)24 Na and 56 Fe (n, p)56 Mn reactions using activation technique and also derived theoretically using compound nucleus model, semiempirical relation and ALICE code. Accuracy around 5% was achieved in measurement of these reaction cross-sections which is better compared to existing literature values.
