Abstract
Lattice vibrations should convert those x-ray absorption edges that are rounded and suppressed by final-state interactions into divergently enhanced, peaked thresholds. However, calculations indicate that the enhancement effect is slightly smaller (by a factor ≅3) than needed if the divergent peak is to be observed in spite of lifetime broadening.Keywords
