We propose to investigate the reactions
pd->3He eta and
pd->3He eta' near threshold using the
The identification of the outgoing 3He
and determination of the four momentum will be provided by
using drift chambers and scintillation walls.
With this information it is possible to calculate the missing
mass of the unobserved particle X of the reaction
pd->3He X, which leads to a full event
reconstruction in the case of the above mentioned two particle
final states of interest.
The new deuterium regeneration system for both the experiments
COSY-11 and ANKE will be used during the deuterium cluster beam
Since the installation COSY-11 takes advantage of the internal cluster target (single particle interaction, no target windows) in combination with a stochastically cooled beam, in view of its high luminosities this experimental setup is suited well for taking high precision data in the near threshold region.
