Abstract
A transmission grating is used to nondestructively analyze a low source temperature (6–60 K) beam of helium for small clusters. He2 and He3 are clearly resolved in first order diffraction. The relative ionization and fragmentation probabilities are measured and lend support to a recent mass spectrometer experiment claiming detection of He2.Keywords
