Abstract：
Studies of γγ interactions are performed with the KLOE detector, without tagging of the outgoing e⁺e^－. The data sample is from an integrated luminosity of 240 pb^－1. It was collected at the φ-factory DAΦNE with e⁺e^－ beams colliding at √s~1 GeV, below the φ resonance peak. We present preliminary results concerning the observation of the γγ→η process and the evidence for γγ→π⁰π⁰ production at low π⁰π⁰ invariant masses.
