Next-to-next-to-leading contributions to the cross section a(e+e--+ T+T-) at energies close to threshold are analysed, taking into account the known non-relativistic effects and U((r2) corrections. The numerical changes with respect to previous works are small, but the new corrections give a true es
The angular distributions of the unpolarised differential cross section and tensor analysing power A xx of the dd β Ξ±Ξ· reaction have been measured at an excess energy of 16.6 MeV. The ambiguities in the partial-wave description of these data are made explicit by using the invariant amplitude decompo
