Photodisintegration of 11Li was accomplished by sending a beam of 11Li at 28 MeV/nucleon through the equivalent photon field of a lead target. By measuring the complete kinematics of the disintegration products, 9Li+n+n, we constructed the correlation of the angle between the two neutrons in the rest frame of the 11Li. The correlation is independent of angle. This result argues against the existence of a bound dineutron in the ground state of 11Li. © 1996 The American Physical Society.
