摘要

A new ¹¹Be(d,p)¹²Be transfer reaction experiment was carried out in inverse kinematics at 26.9A MeV, with special efforts devoted to the determination of the deuteron target thickness and of the required optical potentials from the present elastic scattering data. In addition a direct measurement of the cross section for the 0₂ ⁺ state was realized by applying an isomer-tagging technique. The s-wave spectroscopic factors of 0.20_−0.04 ^+0.03 and 0.41_−0.11 ^+0.11 were extracted for the 0₁ ⁺ and 0₂ ⁺ states, respectively, in ¹²Be. Using the ratio of these spectroscopic factors, together with the previously reported results for the p-wave components, the single-particle component intensities in the bound 0⁺ states of ¹²Be were deduced, allowing a direct comparison with the theoretical predictions. It is evidenced that the ground-state configuration of ¹²Be is dominated by the d-wave intruder, exhibiting a dramatic evolution of the intruding mechanism from ¹¹Be to ¹²Be, with a persistence of the N=8 magic number broken.
