Nanosecond pump{endash}probe photoelectron spectroscopy by means of synchrotron radiation from 6 to 130 eV anticipates the application of new short-wavelength sources with comparable photon energies but shorter pulse durations. The influence of pulsed-UV source characteristics on photoelectron spectrosocpy experiments on solid surfaces, including space-charge effects, is examined. A resonant photoemission experiment is presented to illustrate the use of tunable photon energies in pump{endash}probe photoelectron spectroscopy involving core levels, and a new autoionizing resonance is reported in which electrons laser excited into a GaAs(110) surface state are emitted when a Ga 3{ital d} surface core exciton decays. {copyright} {ital 1996 Optical Society of America.}
