{sup 91}Nb has been recently suggested as a candidate for a cosmic-ray chronometer. To use {sup 91}Nb as such, the relative production cross sections of {sup 91}Nb and {sup 91}Nb in the cosmic rays must be known. These isotopes are produced in the cosmic rays by spallation reactions of Mo and heavier elements on interstellar hydrogen. We have bombarded a natural Mo target with 1.85-GeV protons from the LBL Bevatron. The cross sections for the production of {sup 91,92}Nb and 29 other isotopes with 75 {le} A {le} 97, 35 {le} Z {le} 42 will be presented and compared with theoretical calculations.
