Molecular polarization in molecular hydrogen (CELGAS) — •Alexander Vasilyev — Petersburg Nuclear Physic Institute, Gatchina, Russia

Conventional polarized hydrogen or deuterium targets (storage cell fed by an atomic beam source) used in experiments at storage rings do not show significant increase in a target densities since a last decade. The use of molecules where both nuclei are polarized instead of polarized atoms to feed a storage cell may be the one of the possible ways to improve this situation.

The present project aims on the extension of the studies of nuclear polarization of hydrogen molecules from recombination of polarized atoms [1] performed at IUCF, NIKHEF and HERMES/DESY. Experimental technique and first results will be presented.

Supported by the ISTC, project 1861.
