Description
The total cross section for η production in deuteron-deuteron interactions has been measured at four different kinetic energies, from 0.7 MeV to 3.7 MeV above threshold. The squared amplitude is consistent with a constant value of |f|2=(24.6±1.2±1.7) nb/sr close to threshold (14<pη<40 MeV/c). Assuming that the π0-η mixing reaction mechanism is dominant, this result allows a prediction of (dσ/dΩ)(π0)=(8.3±0.5±0.6) pb/sr for the cross section of the isospin-forbidden reaction d+d → α+π0 at the η-threshold energy.
