Description

This publication briefly reports a study which aimed at the determination of the state period at 180 keV of 99Tc or at giving at least an upper limit of it. The authors used the method of delayed coincidences. The experimental device is presented as well as its principle diagram. Graphs of recorded data are proposed and briefly discussed. Reprint of a paper published in 'Comptes Rendus des Seances de l'Academie des Sciences', T. 240, Session of April 4, 1955, p. 1525-1527
