Experimental cross-sections for the nuclear reactions Mo(p,x)Tc,Mo, Nb and Zr were measured up to 100 MeV, carring out at separated sector cyclotron of the Heavy Ion Research Facility in Lanzhou, using the stacked-foil activation technique. The cross-sections of these nuclides in this work fill the gap in 75–100 MeV energy range. In addition, our experimental results were compared with the previously published values taken from EXFOR database and the theoretical calculations predicted by TALYS-1.95 code with six level density models, which are important input parameters affecting the excitation functions. In terms of results, our measurements show good agreement with the theoretical calculations for most of the radionuclides. Level density models still needs to be further optimized in the description of excitation functions.
