Comparing the spectra acquired during two series of irradiations, the peak intensities of the 178m2Hf isomer have been found to be higher at the end of each series, while the intensities of the 150Eu and 133Ba peaks, which are present in the isomeric target, remain stable. This gives a support to the hypothesis that some additional activity is produced during irradiation. The half-life of this activity appears to be several days.
