Abstract
An experimental search for a new low-energy isomer in the 186Re nucleus was carried out. The existence of such an isomer was recently proposed to explain the results from experiments on the stimulated de-excitation in the laser plasma of the familiar 186mRe isomer with energy E* = 149 keV and a half-life of 2 × 105 years. The experimental result corresponds to this assumption but requires further confirmation and refinement.
