The production cross-sections for the medical isotope 99 Mo were measured using 100 Mo(n, 2n) reaction at average neutron energies of 10.95 ± 0.45, 13.97 ± 0.68, 16.99 ± 0.53 and 20.00 ± 0.58 MeV using the off-line γ-ray spectroscopy. The neutrons of desired energies were generated using 7 Li (p, n) reaction at 14UD BARC-TIFR Pelletron facility, Mumbai, India. The experimentally measured data from the present work have been compared with the existing data libraries like, ENDF/B-VII.1, JENDL-4.0, JEFF-3.2 and CENDL-3.1. The results were also reproduced and compared with the theoretical nuclear modular codes like TALYS-1.8, and ALICE-2014. A modified set of parameters is also used to fit the existing data more accurately. The present findings show a good agreement with the theoretical as well as with the existing experimental data in different data libraries.
