Abstract: (APS)

For the charge-symmetry-breaking reaction d+d→He4+π0 at Td=0.8 GeV around 100° c.m., an upper limit on the production cross section of ≈0.8 pb/sr is obtained. This represents about a factor of 20 improvement on previous measurements, but is still a factor of 5 above expected violations.
