Figure 4: Two-particle correlation identifies ArXe isotopes.
From: Probing the tunnelling site of electrons in strong field enhanced ionization of molecules
(a) Measured time-of-flight mass spectrum of the Xe+ isotopes. (b) Correlations between the times-of-flight of the Coulomb exploding Ar+ and Xe+ following two-side double ionization of ArXe. Each sharp stripe stands for one ArXe isotope. The unit for the colour scale is counts.
