The line width of the first excited state of 133Cs has been measured using the Mössbauer method. Our gamma ray source was 133BaTiO3 in free space. When the absorber, CsCl, was placed between two parallel flat plates, narrowing of the net width by as much as 8.7% was observed for the plate separation distance b=2.13 mm. This result implies that the lifetime of the 81 keV energy level of 133Cs is increased to 6.87 ± 0.11 ns. This value is 9.6% larger than the standard value of 6.27 ±0.02 ns.
