A search for resonance states of [superscript12]Li

Abstract

The discovery of ¹¹Li halo nuclei structure sparked the development of research of exotic nuclei close to the neutron drip line. This includes research on ¹²Li which is unbound beyond the neutron drip line. The question about ¹²Li structure is still open and some studies have uncovered certain properties of ¹²Li like observed resonance states but these have contradictory information about these states. The goal of this study is to find any resonances of ¹²Li by examining a neutron transfer reaction and comparing the results to previously observed resonances for similarities or differences in these results. This experiment was done at the IRIS facility located at TRIUMF where a ¹¹Li beam of 80.3 MeV interacted with a deuterium target to induce a neutron transfer reaction ¹¹Li(d,p)¹²Li. This thesis will cover the analyse of the data for deriving the excitation spectrum.
