Some characteristics of multipion systems as a function of their transverse momenta are studied in ..pi../sup -/p interactions at p=40 GeV/c. It is found that the average transverse momentum of the system increases with increase of the effective mass and is practically independent of the number of particles and the charge of the system. It is shown also that the noninvariant differential cross sections for (m..pi..) systems are satisfactorily fitted by an exponential exp(-(E/sub perpendicular/-M)/T) with Tapprox. =130 MeV. The value of the parameter T is a weak function of the number of particles and charge of the (m..pi..) system and also of its effective mass.
