I (J P )= 1( 7+ ) Status: 2

Discovered by COOL 66 and by WOHL 66. For most results published before 1974 (they are now obsolete), see our 1982 edition Physics Letters 111B (1982). This entry only includes results from partial-wave analyses. Parameters of peaks seen in cross sections and invariant-mass distributions around 2030 MeV may be found in our 1984 edition, Reviews of Modern Physics 56 No. 2 Pt. II (1984).

COMMENT

1 Preferred solution 3; see CORDEN 76 for other possibilities. 2 The two entries for CORDEN 77C are from two di erent acceptable solutions. 3 This coupling is extracted from unnormalized data. 4 The published sign has been changed to be in accord with the baryon- rst convention. 5 An upper limit. 6 The upper limit on the G3 wave is 0.03.
