Natural tellurium has been activated with thermal neutrons $(kT=22\mathrm{}\mathrm{meV})$ and with quasistellar neutrons $(kT=25\mathrm{}\mathrm{keV}).\mathrm{}$ By analyzing the ground state decay of the odd isotopes as a function of time, information on the partial capture cross sections to the isomeric states could be determined with systematic uncertainties of 3–8 %. Additionally, the decay parameters of some isomers could be significantly improved. These results are of relevance for s-process nucleosynthesis.
