Characterization of doping levels in heteronuclear, gas-phase, van der Waals clusters and their energy absorption from an intense optical field
A simple mass spectrometric method has been developed to quantify dopant
levels in heteronuclear clusters in the gas phase. The method is demonstrated
with reference to quantification of the water content in supersonic beams of
water-doped argon clusters. Such doped clusters have assumed much importance in
the context of recently-reported doping-induced enhancement in the emission of
energetic charged particles and photons upon their interaction with intense
laser pulses. We have also measured the energy that a doped cluster absorbs
from the optical field; we find that energy absorption increases with
increasing level of doping. The oft-used linear model of energy absorption is
found to be quantitatively inadequate.Comment: To appear in Chemical Physics Letter
