| Abstract: | The present paper deals with the experimental determination and the critical evaluation of Qo, the ratio of the resonance integral (Io) to the 2200 m.s–1 cross-section ( o) for 57 analytically interesting (n,  ) reactions, including a revision and updating of formerly published results for 13 isotopes. Full account is given for deviations from the ideal epithermal neutron flux distribution. The Budapest-Gent cooperative determinations, yielding parallel but independent results, lead to recommended Qo-values with an average uncertainty as low as  3%. Finally, with the aid of independently evaluated or measured o-data, a list of recommended Io-values is given. |
