∗OMITTED FROM SUMMARY TABLE
Seen in the isospin-1 K N cross section at BNL (LI 73, CARROLL 76)
and in a partial-wave analysis of K − p → Λπ 0 for c.m. energies
1560–1600 MeV by LITCHFIELD 74. LITCHFIELD 74 finds J P =3/2− . Not seen by ENGLER 78, CAMERON 78C, OLMSTED 04,
nor by PRAKHOV 04.
Neither ZHANG 13A nor SARANTSEV 19 see any evidence for thisstate.
