Abstract

Results are presented from an isobar-model partial-wave analysis of a high-statistics sample of the neutral

3 π

system produced in forward charge exchange. Large forward phase motions relative to an exotic reference wave are seen for partial waves with the quantum numbers of the

A_{1}

and of the previously unobserved isoscalar companion (

` ` H''

) of the
