Most of the results published before 1973 are now obsolete and have been omitted. They may be found in our 1982 edition Physics Letters 111B 1 (1982). This entry only includes results from partial-wave analyses. Parameters of peaks seen in cross sections and in invariant-mass distributions around 2100 MeV used to be listed in a separate entry immediately following. It may be found in our 1986 edition Physics Letters 170B 1 (1986).
