Abstract

Resonant structure is studied in the 1.5-to-1.9-GeV mass region of the neutral four-pion system in the reaction π+n→pπ+π+π-π- at 6 GeV/c incident momentum. The ρ0 and A2± content are determined as a function of the four-pion mass. The 4π mass spectrum is best fitted by two resonances, both of which decay predominantly into ρ0π+π-, each with evidence for an appreciable A2π component.
