Abstract By means of the activation technique the excitation functions for the reactions93Nb(n,2n)92mNb(10.15d),103Rh(n,2n)102mRh(2.9y), and103Rh(n,2n)102gRh(206d) were measured with an average total uncertainty of about ±8% between 10 and 20 MeV neutron energy. In addition the total93Nb(n, 2n) cross-section was compared with the59Co(n, 2n) cross-section at 16.8 MeV by direct neutron detection using the time-of-flight technique. The results are compared with statistical theory, especially with theoretical expectations for the isomeric cross-section ratios, which are only in reasonable agreement with the experiment if one assumes a ground state spinI g=5 for92Nb andI g=2 for102Rh.
