It is argued that the amplitudes of the production of n soft scalar particles by one or a few energetic ones in theories such as {λ}cphi⁴ have the exponential form Aₙ{∝} {}n! exp[1/{λ}F({λ}n,{ε})], in the regime {λ}{→}0, {λ}n=fixed, {ε}=fixed, where {ε} is the typical kinetic energy of outgoing particles. Existing results support this conjecture. Several new analytical and numerical results in favor of the exponential behavior of multiparticle amplitudes are presented.
