Abstract
Helium gas is being expanded through a pre-cooled 5 μm nozzle in a supersonic gas jet at low temperatures. Containing small clusters this gas jet passes a transmission diffraction grating, separating clusters of different masses. This mass selected cluster beam is ionized using a Ti:Sa Laser. The Coulomb exploding ionic fragments are measured with the COLTRIMS technique, giving direct access to the square of the vibrational wavefunction of 4He2, 4He3 and 4He23He.
