Abstract
Quantum interference in spontaneous emission from a four-level atom is investigated. The atom has two upper levels coupled by the same vacuu m modes to a common lower level and is driven by a coherent field to a n auxiliary level. Interference can lead to the elimination of a spect ral line in the spontaneous emission spectrum and spontaneous emission cancellation in steady state.
