摘要：
Excitation functions of the Nb-93(p,n)Mo-93m and Nb-93(p,pn)Nb-92m reactions were measured from threshold energies to similar to 20 MeV by employing stacked foil activation technique in combination with the off-line gamma-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 Cu-nat(p,x)Zn-62 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 Nb-93(p,n)Mo-92m 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 Nb-93(p,pn)Nb-93m reaction, present data agree very well with the literature data and the theoretical values. (C) 2018 Elsevier B.V. All rights reserved.
