Van-der-Waals clusters composed of two or more Molecules show fascinating quantum phenomena. Compared to covalent bound molecules, they exhibit huge internuclear distances and small binding energies. Ionizing these clusters with intense laser fields yields insight into their dimension, as well as geometrical structure.

So far we investigated the following subjects:

	Argon and Neon dimers, trimers and tetramers	Helium trimers	Helium Efimov trimers
	Helium dimers	He2 field induced dynamics
