The experimentally determined average charged-particle multiplicities, , of the systems, X, produced in the following reactions for 147 GeV/c incident pion momentum are presented as functions of the square of the invariant mass of X, M/sub x//sup 2/, and of *t*: ..pi../sup -/p ..-->.. ..pi../sup -//sub fast/X, ..pi../sup -/p ..-->.. pX, ..pi../sup -/p ..-->.. ..delta../sup + +/X, ..pi../sup -/p ..-->.. (..pi../sup -/..pi../sup +/)/sub rho//sup 0/X, and ..pi../sup -/p ..-->.. ..lambda../sup 0/X. Details of the analysis are discussed. These data can be fit by the expression = A + BlnM/sub X//sup 2/ + C*t* and the coefficients obtained for B are equal within their uncertainties. C is significantly different from zero only for ..pi../sup -/p ..-->.. ..pi../sup -//sub fast/X.
