Abstract:
It is shown that laser evaporation of a solid target followed by adiabatic expansion can be used to produce cold beams of neutral small open shell molecules. LIF is applied to detect CuH (X1Σ), CH (X 2ϖ), SiH (X 2ϖ), CuO (X 2ϖ), and FeO (X 5Δ). A production of 109±1 molecules/sr in a single pulse is obtained for SiH. For a copper target, the optical emission of the jet plume is discussed.
