Atomic clusters can be used for precise light-matter interaction studies. Rare gas clusters for example can serve as ideal model systems with a simple geometric and electronic structure. In particular, mixed clusters can be utilised to disentangle and analyse the dynamics of surface and bulk in a core-shell system. Using a picosecond laser with a wavelength of 263 nm, Xe/Kr clusters were ionised and measured via time-of-flight spectroscopy. Different mixtures of Xe and Kr and varying cluster sizes are compared and implications for the structure and properties of Xe/Kr clusters in intense light pulses are discussed.
