Directional X-ray and gamma emission in experiments in condensed matter nuclear science

The absence of energetic particles commensurate with the energy produced in the Fleischmann–Pons experiment hinders our ability to sort out the microscopic physics involved. Models that we have studied for excess heat are based on the fractionation of the large nuclear quantum to a large number of much smaller quanta. These models predict that it should also be possible to up-convert vibrational quanta to produce nuclear excitation. Such a mechanism could produce collimated X-ray and gamma emission. Collimated X-ray emission near 1.5 keV has been reported by Karabut. Other examples of collimated X-ray and gamma emission have been described in the literature.
