The Demonstration of the Feasibility of the Tuning and Stimulation of Nuclear Radiation. Gamma Ray Laser
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. Our proposal has been that the key to the excitation of significant levels of multiphoton phenomena lay in the use of small oscillating fields to manipulate the greater ferromagnetic and ferroelectric fields in which nuclei were immersed. Unfortunately, such materials are almost always magnetostrictive or piezoelectric and concern had lingered that all coherent phenomena would be overwhelmed and degraded by periodic Doppler shifts produced by vibrations excited by such mechanical efforts. In the past year we completed an experiment in which we dressed nuclear states with photons from the periodic oscillation of magnetization transported by spin waves through a medium unable to propagate vibrations. Large effects were found to confirm our models.
