Study of 10Li via the 9Li(2H, p) reaction at REX-ISOLDE

Summary, in English

The ⁹Li + ²H reaction has been investigated at 2.36 MeV/u at the REX-ISOLDE facility. In this Letter we focus on the ¹⁰Li + p channel which potentially holds spectroscopic information on the unbound nucleus ¹⁰Li. The experimental excitation energy spectrum and angular distribution are compared with CCBA calculations. These calculations clearly support the existence of a low-lying (s) virtual state, with a (negative) scattering length of the order a_s ∼ 13 - 24 fm and a p_{1 / 2} resonance with an energy of E_r ≃ 0.38 MeV and a width of Γ ≃ 0.2 MeV.
