TL;DR
This study investigates the surface localization of the dineutron in $^{11}$Li, using knockout reactions and correlation measurements to reveal its position and support density-dependent formation models.
Contribution
It provides the first measurement of the correlation angle between neutrons as a function of intrinsic momentum, confirming dineutron localization at the nuclear surface.
Findings
Dineutron localized at approximately 3.6 fm from the nucleus center.
Correlation angle measurements support surface localization.
Results align with density-dependent dineutron formation theories.
Abstract
The formation of a dineutron in the nucleus Li is found to be localized to the surface region. The experiment measured the intrinsic momentum of the struck neutron in Li via the 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 fm. The results also support the density dependence of dineutron formation as deduced from Hartree-Fock-Bogoliubov calculations for nuclear matter.
