AB  - Spontaneous emission from an excited atomic state reflects the properties of the surrounding vacuum field. By placing the atom near a metallic surface or in a cavity, one can modify the spectral density of the vacuum modes coupled to it and either enhance or inhibit spontaneous emission. The spontaneous emission from substates of the 5D//5/////2 level of cesium at 3. 49 mu m has been suppressed by passing the atom between two gold mirrors separated by a 1. 1- mu m gap. The atoms travel in the gap for about 13 natural lifetimes without radiating. Substates with maximum angular momentum normal to the mirrors have their emission turned off. Other substates have their radiation rate either decreased or increased by a factor of between 0. 4 and 1. 3. A magnetic field making an angle with the direction normal to the mirrors was used to study the dependence of the spontaneous emission rates on the polarization of the excited atoms in the gap, enabling the anisotropy of the vacuum-field fluctuations between the two closely spaced mirrors to be checked. The deflection of cesium Rydberg atoms attracted to a metallic surface by the dipole image van der Waals force was also observed.
