The demonstration of the feasibility of the tuning and stimulation of nuclear radiation
Abstract
This project concerns the demonstration of the feasibility of the tuning and perhaps even stimulation of nuclear radiation. Theory has indicated that anti-Stokes Raman upconversion of intense but conventional long wavelength sources of radiation produced by scattering from isomeric states of nuclear excitation could lead to significant sources of tunable Gamma-radiation characterized by the natural Mossbauer widths of the lines. This would result in lines with sub-Angstrom wavelengths and widths of a few MHz. Whether or not these processes can reach threshold depends upon the resolution of basic issues lying in an interdisciplinary region between quantum electronics and nuclear physics that have not been previously addressed. It was the purpose of this work to study these issues experimentally. The overall problem being addressed is a broad one that naturally divides into three lines: (1) Coupling pump power into a nucleus, (2) Extracting nuclear excitation with a radiation field, and (3) Insuring material survival. Such a perspective is beyond the scope of a single project and only the second line has been addressed by the work supported by this grant.
