Abstract
The electron-phonon enhancement factor is determined for scandium, yttrium, vanadium, platinum, and palladium solely from specific-heat data. The key to the method is that at high temperatures the electron-phonon enhancement factor is zero. Therefore, if the electronic specific-heat coefficient at high temperatures is calculated and compared with the low-temperature value, both the band-structure density of states and the electron-phonon enhancement factor can be determined.Keywords
