ABSTRACT

We performed a series of experiments employing the two pion production reactions p+d→3He+Πo and p+d→3H+Π+.The two isospin related reactions Differ by a Clabsch Gordan coefficient of 2.We searched for deviations in this ratio in complete angular distributions in the range of the Δ excitation as well as in the vicinity of the η production thres hold.
