Structure Studies of <sup>13</sup>Be
ORAL
Abstract
A variety of structure phenomena such as alpha clustering, neutron halos, and the breakdown of the N=8 shell gap are observed in the beryllium nuclei, making them attractive for nuclear structure studies. The structure of 13Be offers insights into the N=8 shell gap, the nature of the Borromean 14Be nucleus, the influence of the continuum, and the nature of neutron-drip line nuclei.
To study the low-lying structure of 13Be, we performed the 12Be(d,p)13Be transfer reaction in inverse kinematics at ISAC II at TRIUMF. The 12Be beam at 9.5 MeV/u interacted with the novel IRIS solid D2 target. Ejectiles and recoils were detected in an annular silicon detector array and two ΔE-E telescopes, respectively. The excitation energy spectrum showing the resonances in the 13Be continuum, fitted with the response function obtained from GEANT4 simulations, and the angular distribution of the lowest-lying strength will be presented here.
