摘要：

We have performed a search for I=2 multipion resonances (χ - ) in reactions of the type π-n→pχ - , where χ - decays into π-π+π-π- with or without extra π0 mesons. Our results at a π- beam momentum of 7 GeV/c indicate that if these resonant states exist and if they have widths of ≤160 MeV, then they are produced only with cross sections which are one to two orders of magnitude lower than the production cross sections measured for the well-established resonances. © 1968 The American Physical Society.
