Multiphoton dissociative ionization of CS$^+$
POSTER
Abstract
We have studied the dissociative photoionization of a CS$^+$ molecular ion beam in the strong-field regime using $<$50 fs IR laser pulses ($\lambda\sim$790 nm) from a 10 kHz, $\sim$2 mJ (per pulse) Ti:Sapphire laser system. A coincidence three-dimensional momentum imaging method was used to measure all ions and neutrals formed during this multiphoton process. Two prominent channels were observed: charge-symmetric dissociation, yielding C$^+$ + S$^+$, and charge-asymmetric dissociation, yielding C + S$^{2+}$. The differences between these two channels with reference to their relative production probability, energetics, and angular distributions is the focus of this work.
