In this work, we present the results obatained from 7keV electron impact ionization of O2. The double differential cross sections (DDCS) have been measured for 14 different angles between 20deg -145deg in the present experiment using a hemispherical electrostatic analiser. Measurements have been compared with computed DDCS within the B1 approximation for twice atomic oxygen. The experimental-to-theoretical ratios show clear signature of interference oscillations coming from the coherent emission from the  two centre molecular target.
