Description
Summary:Nuclear γ-ray-resonant superradiance is discussed, comparing Dicke's original approach 1 and recent extensions 2 , 3 of Scully et al. 2-5 involving conditional excitation to the classical resonant-scattering 6-10 and the Hannon-Trammell 11-14 quantum theories. Relevant questions are whether the sample is optically thin or thick in the excitation and re-radiation processes, the role of superpositions between ground and excited states, Fermi's golden rule, and decoherence due to spatially-dependent near-field interactions 15-17 . The relation of these considerations to experimental results is discussed.
