英文摘要we describe a collinear velocity-map photoelectron imaging spectrometer, which combines a wiley-mclaren time-of-flight mass analyzer with a dual-valve laser vaporization source for investigating size-selected cluster and reaction intermediate anions. to generate the reaction anions conveniently, two pulsed valves and a reaction channel are employed instead of premixing carrier gas. the collinear photoelectron imaging spectrometer adopts modified velocity-map electrostatic lens, and provides kinetic energy resolution better than 3%. the performance of the instrument is demonstrated on the photodetachment of si(4)(-) at 532 and 355 nm, and si(3)c(-) at 532 nm, respectively. in both cases, photoelectron spectra and anisotropy parameters are obtained from the images. for si(4)(-) the spectra show two well-resolved vibrational progressions which correspond to the ground state and the first excited state of the neutral si(4) with peak spacing of 330 and 312 cm(-1), respectively. preliminary results suggest that the apparatus is a powerful tool for characterizing the electronic structure and photodetachment dynamics of cluster anions.
