Research:

The general field of basic research is quantum nucleonics. I am interested in the interaction of electromagnetic waves with matter, in the energy region corresponding to gamma radiation. I am particularly interested in the possibility of developing a gamma-ray laser. I have developed a theory of resonant gamma-ray forward scattering which gives a clear physical explanation of interesting observed physical phenomena such as; the "speed-up" effect, dynamically beating and pi phase shift induced transparency. I am interested in applying quantum optics results to gamma radiation. These include the observation of stimulated emission of gamma radiation, witch to date has not been observed.
