Abstract

Unbound positive-parity states in 10Li have been populated with a two-proton removal reaction from a 71 MeV/u 12B beam. The 9Li fragments and emitted neutrons were measured with the MoNA-LISA-Sweeper setup. The measured decay energy spectrum was best fit with three states at 110±40, 500±100, and 1100±100 keV decay energy. This is the second observation of a resonance below 200 keV. The lower two states likely belong to the expected 1+, 2+ doublet.
