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

The Li9+H2 reaction has been investigated at 2.36 MeV/u at the REX-ISOLDE facility. In this Letter we focus on the Li10+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 as∼13-24fm and a p1/2 resonance with an energy of Er≃0.38MeV and a width of Γ≃0.2MeV.
