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 (X
1 ), CH (X
2 ), SiH (X
2 ), CuO (X
2 ), and FeO (X
5 ). 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. |
