Breakup and electromagnetic response of light weakly-bound dicluster systems

Abstract

This study is focused on the breakup and electromagnetic response of light weakly-bound dicluster nuclei. The cluster picture in the case of ⁷Li is shown to be a very good approximation and in this framework we calculate nuclear structure observables. We solve the Schrödinger equation for the relative motion both for discrete and continuum states and this automatically takes the role of resonances into proper account. A concentration of strength in the low energy continuum, solely due to the weakly-bound nature of the bound states is seen and explained as a favorable matching between the wavelengths of the initial and final states. Finally, preliminary results on form factors are briefly outlined and their microscopic derivation as well as utilization in reaction studies are discussed.
