Depending on the excited electronic state, the Cs impurity remains on the droplet surface or it is ejected. Upon subsequent photo-ionization of the excited Cs atom the resulting Cs+ cation may either be ejected or come back to the droplet, depending on the time delay between photo-excitation and photo-ionization. We have calculated the critical time delay separating these two different behaviors, as well as final ion velocities. These observables will be used for future comparison with planned pump-probe experiments.application/pdfeng(c) Springer Verlag, 2019Dinàmica de fluidsHeliFluid dynamicsHeliuminfo:eu-repo/semantics/article6934672023-01-18info:eu-repo/semantics/openAccess
