Angular distribution of neutrons emitted in(11Li,9Li) breakup reactions

The angular distribution of neutrons emitted in ${(}^{11}$Li${,}^9$Li) breakup reactions is calculated directly from one of the reaction mechanisms, viz. Coulomb dissociation. The shape of the calculated distribution agrees quite accurately with recently measured neutron data. This provides a test of the calculated dipole strength in ${}_{}{}^{11}{}_{}{}^{}\mathrm{Li}$ at low excitations.
