Nuclear {gamma}-ray-resonant superradiance is discussed, comparing Dicke's original approach 1 and recent extensions 2,3 of Scully et al. 2-52, 3, 4, 5 involving conditional excitation to the classical resonant-scattering 6-106, 7, 8, 9, 10 and the Hannon-Trammell 11-1411, 12, 13, 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 15-1715, 16, 17. The relation of these considerations to experimental results is discussed.
