Using a low-temperature growth technique and an Fe whisker sample, atomically-uniform films of Ag on Fe(100) are prepared. Extremely sharp quantum-well peaks are obtained in these films, as peak broadening from thickness variation is eliminated. The quality of the spectra allows the observation of quantum-well peaks in films over 100 monolayers thick. Quantum-well peaks from both the sp and d states have been observed and used to map the associated bands. The elimination of broadening from thickness variation allows for the interpretation of the peak linewidths in terms of the quasiparticle lifetime and interfacial reflectivity, and the phonon contribution can be deduced from the temperature dependence of the spectra.
