Born-Oppenheimer and fixed basis models for vibrations in a metal lattice and phonon fluctuations
Abstract
Last year we presented results on a model for Karabut's collimated x-rays which seemed to give good agreement with experiment. When writing up the model for publication, we found an error, which forced us to pursue a different version of the model. The issue in the earlier model was that phonon-nuclear coupling based on the relativistic interaction by itself is insufficient to allow for coherent energy exchange between vibrations and nuclear excitation with as much up-conversion as seems to occur in the Karabut experiment. In the new model, we combine phonon-nuclear interactions with electron-phonon interactions to increase the fractionation power of the combined system.
