High-statistics search for A/sup 0//sub 1/ and H/sup 0/ in. pi. /sup -/p. -->. pi. /sup +/. pi. /sup -/. pi. /sup 0/ at 8. 4 GeV/c

A search is made for the hitherto unobserved neutral J/sup P/ = 1/sup +/ objects A/sub 1//sup 0/ and H/sup 0/ produced in the reaction ..pi../sup -/p ..-->.. ..pi../sup +/..pi../sup -/..pi../sup 0/ ..-->.. ..gamma gamma.. n at 8.4 GeV/c. Both charged pions and both ..gamma..'s are measured in the Charged and Neutral Spectrometer at the Argonne ZGS. Preliminary results from a first-pass analysis of 45 percent of the data, containing approximately 900 events/10MeV/c/sup 2/ mass bin at 1100 MeV/c/sup 2/ are reported. Strong peaks at the eta, ..omega.., A/sub 2/, and ..omega..(1670) dominate the spectrum. The possible presence of less prominent structure is discussed.
