Abstract

Electron spectra from Arn (n ≤ 24 000) and doped Ar-CS2 clusters are studied experimentally at laser intensities of about 1015 W cm−2. More than an order of magnitude enhancement in the electron yield is observed in the case of doped Ar-CS2 clusters. The enhancement observed is argued to be because of the presence of species with low ionization potential, CS2, in the cluster. Similar enhancement is also observed in K-shell emission when comparison is done between pure Arn and mixed Ar-(CS2) clusters under identical experimental conditions of laser irradiation. We also address the effect of doping CS2 clusters with dopant, Ar, which has higher ionization energy. We demonstrate a simple method for the characterization of doping level based on the Rayleigh scattering measurements.
