On the Electron-Phonon Interaction in Normal Metals. I

The effect of the electron-phonon mteractron on the densIty of one-electron states in d metal IS clrscussed III consIstence WIth electrIc conductlvity By the Ube of the same Hamiltoman and the same JpprOximatlOn as III Bardeen's theOlY of resIstrvIty, one obtams the electron mass shIft Am/m=O 32 for sodlUm m good agreement with the experImental data on speCIfic heat Based on Ehashberg's formalIsm, on the other hand, It IS shown that the bare electron mass appears m statrc conductlvity and anomalous skm effect. Jt IS suggested that the electron mass IS frequency-dependent m the mfrared regIOn
