    In this work, theoretical predicted production cross section were made using COMPLETE, EMPIRE-3.2 and TALYS-1.95(G) reaction model codes for the production of medically important 88Y, 89Zr, 90Y and 99Mo radionuclides in the interaction of α-projectile with 89Y and 96Zr-targets at ≈10-60 MeV. The theoretical predicted production cross sections were compared with the experimental data available in the EXFORE database. The TALYS-1.95(G) code predicted production cross sections of medically important 88Y, 90Y, and 89Zr radionuclide, in general, are found to be in good agreement with experimental measured production cross sections over the entire energy range except for 99Mo radionuclide. Pearson‟s statistical coefficients confirmed a strong positive correlation between TALYS-1.95(G) codes predicted and experimentally measured production cross section except for 99Mo. Furthermore, it was found that the TALYS-1.95(G) predicted and experimentally measured production cross-sections in general attained maximum values below ≈45MeV α-energy for medically important 88Y, 90Y, and 89Zr radionuclides via complex (α,x) channel. Thus the obtained result can be used as reference cross-section data for optimized production of medically important 88Y, 90Y, 89Zr and 99Mo radionuclides using single α + 89Y, 96Zr system.
