IDA Gamma-Ray Laser Annual Summary Report (1990): Investigation of the Feasibility of Developing A Laser Using Nuclear Transitions

Abstract

This paper compares two processes that can occur, under different conditions, in the same system of nuclei: amplified spontaneous emission (ASE) and superfluorescence (SF). It concludes that the (Trammell and Hannon) conditions for the occurrence of ASE are more restrictive than those for the occurrence of SF. Therefore, the conclusion by some authors based on an analysis of ASE, that coherent electromagnetic emission from a nuclear system is not feasible, is incorrect. The paper examines the feasibility of nuclear SF in 60Co. It concludes that SF will occur in the excited state obtained by thermal neutron pumping with fluxes ranging from 10.18 to 10.23 neutrons per second.
