A unified description of the structure and electromagnetic breakup of $^{\bf 11}$Be

Abstract

We study both the static properties of 11 Be and its reaction dynamics during electromagnetic breakup under a unified framework. A many-body approach -the antisymmetrized molecular dynamics (AMD) is used to describe the structure of the neutron-halo nucleus, 11 Be. The same AMD wave function is then adapted as an input to the fully quantum theory of Coulomb breakup under the aegis of the finite range distorted wave Born approximation theory. The calculated observables are also compared with those obtained with a phenomenological Woods-Saxon potential model wave function. The experimental core-valence neutron relative energy spectrum and dipole response along with other observables are well described by our calculations.
