Özet
We report the measurement of lambda, the electron-phonon mass enhancement parameter, for the spin-orbit-split Gamma surface state on Au(111). lambda is determined from the change of the photoemission linewidth as a function of temperature. The difference between the normal emission lambda=0.34 +/- 0.01 and midband lambda=0.30 +/- 0.01 is explained as increasing bulk penetration of the surface state as it approaches the Fermi level.
