Abstract

Photodisintegration of Li11 was accomplished by sending a beam of Li11 at 28 MeV/nucleon through the equivalent photon field of a lead target. By measuring the complete kinematics of the disintegration products, Li9+n+n, we constructed the correlation of the angle between the two neutrons in the rest frame of the Li11. The correlation is independent of angle. This result argues against the existence of a bound dineutron in the ground state of Li11. © 1996 The American Physical Society.
