Ab-initio calculations have been able to reproduce emergent phenomena such as the formation of clusters in nuclei, a prominent feature in light nuclei. A number of ab-initio methods have made predictions for the B(E2; 3/2− → 1/2−) transition strength in the radioactive nucleus 7Be where a prominent α-3 He structure is expected. In order to test and guide these ab-inito methods, we have performed a Coulomb excitation experiment to measure the B(E2; 3/2− → 1/2−) in 7Be. Our current results point to the importance of reproducing cluster features in our nuclear models.
