Abstract A method is described, and results given, for measurements, made at the VVR-M reactor of the Institute of Physics of the Ukrainian Academy of Science, of the total neutron cross sections of the isotopes Re185 and Re187 in the resonance, thermal, and cold regions of the neutron spectrum. The cross section of these isotopes follow the 1/v law with good accuracy below 0.08 eV; however,the positive levels of Re185 are responsible for only 56% of the total cross section in the thermal region, and those of Re187 for only 3%. An analysis of the cross sections shows that the energy of the negative level in Re187 closest to zero is 5 eV≤|e0|≤10 eV; in Re185, |E0|≥10 eV.
