Paper Abstract

A time-of-flight (TOF) mass spectroscopy technique has been used to investigate the expansion dynamics of ionized atoms and clusters ejected from lead target by ultraviolet laser ablation. An angular distributions if ionic species are presented as well as their influence on the deposited film thickness profile is discussed. The influence of the bias voltage of the intake aperture of spectrometer on TOF spectra has been studied. The TOF spectra of ablated Pb-target and the observed Pvn+(n=2-6) peaks are presented. The angular distribution of the mass of ejected ions is described by cosp(θ).
