Method of analysisCrossed channel isospin amplitude analysis of the reaction pN + N ~A The reaction pN -+ NnA can in the crossed channel be described (1236) above 6 GeV/c incident momentum. V. Bakken,' H. Gemow: T. by a set of three independent isospin amplitudes [4] . This set Jacobsen,' P. Lundborg,' J. Makela,' J. Olsson,' M. Pimil,' B. Sellden,' can be suggested in ref. [4] , convenient choices are those illustrated in Fig. 1. The sets of and E.
