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.

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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
