The photo-induced K ∗ vector meson production is investigated for the study of the Λ (1405) resonance. This reaction is particularly suited to the isolation of the second pole in the Λ (1405) region which couples dominantly to the K ̄ N channel. We obtain the mass distribution of the Λ (1405) which peaks at 1420 MeV, and differs from the nominal one. Combined with several other reactions, like the π − p → K 0 πΣ which favours the first pole, this detailed study will reveal a novel structure of the Λ (1405) state.
