Abstract only.Title on abstract: Deep-orbit-electron radiation absorption and emissionThe deep-Dirac level (DDL) electron orbits have been proposed, and rejected, for over 50 years. The rejections have been based on mathematical considerations resulting from the singular Coulomb potential used in the Dirac equations and on lack of observation of such levels. Nevertheless, these orbits explain many things experimentally observed in CF and may be a unique explanation for the low-radiation or nearly radiation-free transmutation measured in both PdD and NiH CF systems, It is important to develop the characteristics of these very deep-orbit, relativistic, electrons and their formation of femto-atoms and molecules in more detail
