Abstract

The s-wave neutron fraction of the 0⁺ levels in ¹²Be has been investigated for the first time through the ¹¹Be(d, p) transfer reaction using a 5 A MeV¹¹Be beam at TRIUMF, Canada. The reaction populated all the known bound states of ¹²Be. The ground state s-wave spectroscopic factor was determined to be 0.28_{- 0.07}^{+ 0.03} while that for the long-lived 0₂⁺ excited state was 0.73_{- 0.40}^{+ 0.27}. This observation, together with the smaller effective separation energy indicates enhanced probability for an extended density tail beyond the ¹⁰Be core for the 0₂⁺ excited state compared to the ground state.
