We present angle resolved photoemission spectra for Ag(111) and Au(111)single crystals in normal emission geometry, taken at closely spaced intervalsfor photon energies between 8 eV and 160 eV. The most dominant transitionsobserved are attributed to f-derived final states located about 16 eV to 17 eVabove EF for both materials. These transitions exhibit very distinct resonancephenomena and selection rules and are reminiscent of the angular momentumcharacteristics of the states involved. The excited electron lifetime is in theattosecond (as) range as determined from the energy width of the observedtransitions. This serves as an alternate approach to the direct determinationof excited electron lifetimes by as laser spectroscopy.
