Abstract

It is shown that the striking energy variation in the pd

\to^{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

He and η

Be channels.
