Abstract
The crux of the present work is to analyze the yield of the residues produced in the 7Li-induced reaction on 89Y target in the low energy range. The experimental yields of 93mMo, which is a significant product in the energy range considered, and other coproduced radionuclides, such as 92mNb, 89Zr, 91mY, and 90mY have been measured within 19–40 MeV energy, and are compared with the compound and pre-compound models in the framework of the statistical reaction model code EMPIRE. The maximum measured yield for 93mMo is 374 MBq/C at 31.3 MeV in a 3 mg/cm2 thick 89Y target corresponding to a cross-section of 396.8 ± 38.6 mb from the 89Y(7Li,3n)93mMo reaction. The model estimations well reproduce the experimental yields of 93mMo. The possible production of stable isotopes has also been estimated theoretically from the model over the experimental energy range. The reaction could be an alternative route for the production of no-carrier-added 93mMo radionuclide provided that the radionuclides are chemically separated from the bulk 89Y matrix.
