Charge radius and dipole response of ${}^{11}$Li

Abstract

We investigate the consistency of the measured charge radius and dipole response of ${}^{11}$Li within a three-body model. We show how these observables are related to the mean square distance between the ${}^9$Li core and the center of mass of the two valence neutrons. In this representation we find by considering the effect of smaller corrections that the discrepancy between the results of the two measurements is of the order of 1.5$\sigma$. We also investigate the sensitivity to the three-body structure of ${}^{11}$Li and find that the charge radius measurement favors a model with a 50% s-wave component in the ground state of the two-neutron halo, whereas the dipole response is consistent with a smaller s-wave component of about 25% value.
