Abstract: The excitation functions of (n, 2n) and (n, α) reactions for the production of long-lived radio nuclides 26Al and 24Na from 27Al have been calculated for 1-20 MeV neutrons. The excitation functions of these reactions are calculated using the codes ALICE-91, EMPIRE-2.19 and TALYS-1.0. The codes account for the major nuclear reaction mechanisms, including direct, pre-equilibrium and compound nuclear ones. The excitation functions of these isotopes have been compared graphically with the evaluated nuclear data file and available experimental data. The results are more or less agreeing up to which energy the experimental data are available whereas ALICE code largely under predicts the data in the energy range 1-20 MeV.
