The depopulation of the quasistable 180 Ta m was studied by irradiating natural Ta samples with strong 60 Co and 137 Cs sources. Decay of the ground state (t 1/2 = 8.1 h) was observed by taking gamma-spectra using a large planar Ge detector in a NaI(Tl) anticoincidence shielding. Clear evidence was
