Investigation of the dd -> He-4 eta reaction has been a part of the experimental programme at the ANKE facility of COSY-Julich. In a first stage measurements were made at two excess energies: 2.6 MeV, 7.7 MeV as well as one energy below threshold for physical background studies. The experimental technique and the results are presented. The total cross sections obtained link well with the existing data, though there is some ambiguity at the higher energies, where sonic earlier data were taken with a polarised beam. Measured angular distributions indicate the onset of higher partial waves at only 7.7 MeV above threshold. |
