Abstract

Photodisintegration of

{}^{11}{Li}

was accomplished by sending a beam of

{}^{11}{Li}

at 28 MeV/nucleon through the equivalent photon field of a lead target. By measuring the complete kinematics of the disintegration products,

{}^{9}{Li}

+n+n, we constructed the correlation of the angle between the two neutrons in the rest frame of the

{}^{11}{Li}

. The correlation is independent of angle. This result argues against the existence of a bound dineutron in the ground state of

{}^{11}{Li}
