Excitation functions of the ⁹³Nb(p,n)^93mMo and ⁹³Nb(p,pn)^92mNb reactions were measured from threshold energies to ∼20MeVby employing stacked foil activation technique in combination with the off-line γ-ray spectroscopy at the BARC-TIFR Pelletron facility, Mumbai. For the 20 MeV proton beam, the energy degradation along the stack was calculated using the computer code SRIM 2013. The proton beam intensity was determined via the ^natCu(p,x)⁶²Zn monitor reaction. The experimental data obtained were compared with the theoretical results from TALYS-1.8 as well as with the literature data available in EXFOR. It was found that for the ⁹³Nb(p,n)^92mMo reaction, the present data are in close agreement with some of the recent literature data and the theoretical values based on TALYS-1.8 but are lower than the other literature data. In the case of ⁹³Nb(p,pn)^93mNb reaction, present data agree very well with the literature data and the theoretical values.
