Abstract : It is shown that the triangle amplitude can be written as the scalar graph multiplied by a factor which contains only the characteristics of the external particles. In the case where the spins of the external particles are summed, their angles averaged, and where only one particle wave set (that is, a set of relative orbital angular momenta among the final state particles) is retained, then this multiplicative factor is just a product of appropriate 3-momenta. The case K(+)p to K 3pi pi at 3 BeV/c is considered; and it is demonstrated that the correct inclusion of threshold factors does not diminish the effect calculated by Halpern and Watson (Phys. Rev. v131 p2674 1963). (Author)
