The annihilation channel p̄p → KLKSπ0π0 was studied with the Crystal Barrel detector at LEAR. This final state with negative C-parity is dominated by the strange resonances K * (892), K1(1270), K1(1400) and K*0(1430). In addition, a JPC = 1+- state is seen in the K * K decay mode. This state could be the isoscalar, axialvector h′1 seen here with a mass of m = (1440 ± 60) MeV/c2 and a width of Γ = (170 ± 80) MeV/c2.
