摘要：

The contribution of phonons to the Hubbard-type exchange interaction parameter is shown to be much smaller than the electron-phonon mass-enhancement parameter λ as a consquence of Migdal's theorem. Application to ZrZn2 and the connection with p-state pairing are briefly discussed. © 1979 The American Physical Society.
