520	3		_aUsing a data sample of 106 million ψ(3686) events collected with the BESIII detector operated at the BEPCII storage ring, we study for the first time the decays χcJ→ϕK0SKπ∓ and χcJ→ϕK+K−π0 in the E1 radiative transition ψ(3686)→γχcJ. The decays are dominated by the three-body decay χcJ→ϕK∗(892)K. We measure branching fractions for this reaction via the neutral and charged K∗(892) and find them consistent with each other within the expectation of isospin symmetry. In the KKπ invariant mass distribution, a structure near the K∗(892)K mass threshold is observed, and the corresponding mass and width are measured to be 14124(stat)8(sys)  MeV/c2 and Γ=8412(stat)40(sys)  MeV, respectively. The observed state favors an assignment to the h1(1380), considering its possible JPC and comparing its mass, width and decay mode to those reported in the Particle Data Group.
