It has been claimed recently that half-lives of radioactive nuclei embedded in metals would be significantly affected by electron screening provided by the metal. The effectwould further be strengthened at low temperatures. We have determined the half-life-of 253Es nuclei embedded in iron at temperatures between 4 K and 50 mK. Our results agree with the room temperature literature value within about 2% and show no dependence on temperature over a range of almost two orders of magnitude. ispartof: Physical Review C vol:76 issue:2007 status: published
