A sharp peak at 1150 MeV c-2 in the pi- pi+ pi- pi+-system in the final state of pBAR He-4-reactions at 0.6 GeV c-1 incident momentum is seen. This system probably has spin-parity = 0+ or 2+, which are possible spin-parity assignments of a glueball.

Abstract
A sharp peak at 1150 MeV c-2 in the pi- pi+ pi- pi+-system in the final state of pBAR He-4-reactions at 0.6 GeV c-1 incident momentum is seen. This system probably has spin-parity = 0+ or 2+, which are possible spin-parity assignments of a glueball.
