Empirical formula for neutron yield for (α, n)‎ reactions from 63cu and 65cu

الملخص EN

The calculated neutron yields from (α, n) reactions are very important in analyzing radiation shielding of spent fuel storage, transport and safe handling.

The cross sections of 63Cu (α, n) 66Ga and 65Cu (α, n) 68Ga reactions are calculated for different α-energies using different sets of programs using Matlab language.

The values deduced energy is from threshold to Eα = 30 MeV and to Eα = 40 MeV for 63 Cu (α, n) 66 Ga and 65 Cu (α, n) 68 Ga respectively.

The weight average cross section was then used to calculate the neutron yields y0 (n / 106 α) for each reaction.

The empirical formula was then suggested to calculate total neutron yield to each isotope.
