Near-Threshold Production of η-Mesons
Colin Wilkin
Abstract
It is shown that the striking energy variation in the p\, d → \, 3 He\, η cross section near threshold is probably due to a final state interaction associated with a large (complex) η-3 He scattering length. The consequences of this hypothesis are studied for the production of the meson in the η-4 He and η-7 Be channels.
