“…An independent check of these results is possible by a study of radiative Se-decays. Until now only very limited information on these modes is available [5,6], because 27 + --+nn +-7 decays are suppressed by about three orders of magnitude with respect to the 2 body decays and the estimate of competing background reactions is difficult.…”

“…The asymmetryparameter of non-leptonic ~+ ~nn + decays is essentially zero, indicating that the angular momentum state of the final pion-nucleon is either pure S-wave or P-wave. The correct parity assignment was established [4][5][6] by measuring the 7-parameter with help of the neutron polarisation in the ~+ ~ n n + mode. An independent check of these results is possible by a study of radiative Se-decays.…”

The radiative 27+--,,nn+7 decay mode was analysed in the 81 cm SACLAY hydrogen bubble chamber exposed to a stopping K-beam at the CERN PS. The pion spectrum was measured up to momenta of 1 50 MeV/c in the 27 rest frame.We obtain the following branching ratios based on 180 27+ --+ nn + ~, and 292 27---+ nn-7 events:F(Z + ~ n n + 7)/F(27 + ~ n n +) = (0.93 ___ 0.10) X 10 -3An unambiguous assignment of S-wave to the 27---* nn-and P-wave to 22+--+ nn + was obtained. The absolute and differential decay rates as well as the parity assignments are in good agreement with theoretical predictions.
