Alignment and Imaging of the CS2 Dimer Inside Helium Nanodroplets

The carbon disulphide ({\mathrm{CS}}_{2} dimer is formed inside He nanodroplets and identified using fs laser-induced Coulomb explosion, by observing the {\mathrm{CS}}_{2}^{+}ion recoil velocity. It is then shown that a 160 ps moderately intense laser pulse can align the dimer in advantageous spatial orientations which allow us to determine the cross-shaped structure of the dimer by analysis of the correlations between the emission angles...
