Moessbauer-Borrmann superradiance
The kinetic behavior of a gamma-ray laser is comprised of an array of isomeric nuclei located at regular lattice sites in a perfect single crystal of dimensions and structure so chosen as to favor anomalous emission into that Borrmann mode having the maximum possible number of component Bragg-reflected beams, which greatly reduces the excitation requirements. The analysis of several hypothetical systems shows that superradiance, rather than amplified spontaneous emission, will then be the preferred mode of deexcitation, provided the nuclei can be pumped rapidly to a short-lived Moessbauer level while preserving crystal integrity. This warrants a search for solutions to the major problems: candidate nuclides, preparation of a storage isomer, and interlevel transfer from storage to lasing state. 10 refs., 8 figs., 2 tabs.
