The cross sections for (n, x) nuclear reactions on terbium and lutetium isotopes

Neutron cross sections have been measured for Lu and Tb isotopes with neutron activation method. Foils of natural lutetium and terbium were irradiated by neutrons produced by neutron generator NG-300/15. To ensure results accuracy and precision the coincidence summing and self-absorption effects have been taken into account. Calculations of efficiency and corrections have been performed with Monte Carlo simulations. The cross section results obtained for 175Lu(n, alpha)172Tm reactions were reported for the first time. Theoretical calculations of excitation functions were conducted with the Talys-1.0 code
