Abstract

The formation of a dineutron in the Li11 nucleus is found to be localized to the surface region. The experiment measured the intrinsic momentum of the struck neutron in Li11 via the (p,pn) knockout reaction at 246 MeV/nucleon. The correlation angle between the two neutrons is, for the first time, measured as a function of the intrinsic neutron momentum. A comparison with reaction calculations reveals the localization of the dineutron at r∼3.6 fm. The results also support the density dependence of dineutron formation as deduced from Hartree-Fock-Bogoliubov calculations for nuclear matter.
