AB  - The radiative decay of Cs atoms excited into the 5D5/2 level and passing between two metallic mirrors spaced by a 1.1-m gap is observed to depend upon their angular momentum. Spontaneous emission at a wavelength of 3.49 m is suppressed for the substates with maximum angular momentum normal to the mirrors, which survive without substantial decay during 13 natural lifetimes. The radiation rate is modified by application of a magnetic field which mixes sublevels having lifetimes in the gap. This experiment illustrates the anisotropy of the vacuum field in confined space. © 1987 The American Physical Society.
