Abstract

The article presents all isotopes studied to date, the analysis of neutron induced fission of which has shown the presence of resonances corresponding to neutron energies close to 0.3 eV and promising for measuring the ROT effect on them. The dominance of one of the two possible components of the partial cross sections at these resonance energies should lead to the fact that the rotation of the compound nucleus before its rupture in one of the two directions will significantly predominate. As a result, the effect size is expected to be significant and with a quite predictable sign. The influence of resonances, the existence of which is assumed in the negative region of neutron energies, will be negligible here compared to the cold and thermal regions previously used to measure the ROT effect.
