The life-time of 133Cs in the first excited state has been measured with the Mössbauer method by placing the absorber, CsCl, between two parallel flat plates and the gamma-ray source, Ba^*TiO3, in the free space. The result is 9.37 ± 0.19 ns, which is 49 percent larger than the standard value 6.27 ± 0.02 ns.
