Abstract: (Elsevier)

BES data on J / ψ → γ ( K + K − π + π − ) are presented. The K ∗ K ̄ ∗ contribution peaks strongly near threshold. It is fitted with a broad 0 −+ resonance with mass M =1800±100 MeV, width Γ =500±200 MeV. A broad 2 ++ resonance peaking at 2020 MeV is also required with width ∼500 MeV. There is further evidence for a 2 −+ component peaking at 2.55 GeV. The non- K ∗ K ̄ ∗ contribution is close to phase space; it peaks at 2.6 GeV and is very different from K ∗ K ∗ ̄ .
