Investigating the 10Li continuum through 9Li(d,p)10Li reactions

Abstract

The continuum structure of the unbound system 10Li, inferred from the 9Li(d,p)10Li transfer reaction, is reexamined. Experimental data for this reaction, measured at two different energies, are analyzed with the same reaction framework and structure models. It is shown that the seemingly different features observed in the measured excitation energy spectra can be understood as due to the different incident energy and angular range covered by the two experiments. The present results support the persistence of the N=7 parity inversion beyond the neutron dripline as well as the splitting of the well-known low-lying p-wave resonance. Furthermore, they provide indirect evidence that most of the ℓ=2 single-particle strength, including possible d5/2 resonances, lies at relatively high excitations energies.
