✦ Synopsis

A new type of negative ion photoelectron spectrometer which utilizes time-of-flight for both ion mass selection and photoelectron energy analysis is described and demonstrated on the 532 nm photodetachment of the well-known O-and 0, ions as well as the 0; cluster ion. Photoelectron spectra of 0, at 355 and 532 nm depend on laser power, suggesting that photodissociation competes with photodetachment at both wavelengths.
