THIN TARGET YIELDS AND EMPIRE-II PREDICTIONS ON THE ACCELERATOR PRODUCTION OF TECHNETIUM-99m

Thin target yields of 99mTc radionuclide produced on accelerator by means of the reactions natMo(p,x) from threshold up to 18 MeV are given. The experimental data have been measured employing the stacked foil activation technique. To the best of our knowledge the theoretical analysis of the excitation functions based on the EMPIRE-IIcode, used for the first time, gave good agree the theoretical and experimental data.This code could be used to predict the cross sections of the isomeric states for the 100Mo(p,x)99mTc. Effects of various free parameters used in the calculations are also discussed. A significant contribution of pre-equilibrium CN component has been observed at these energies. Methods of cyclotron production of 99mTc are considered
