Selective Population Of Unbound States In Li-10
Nuclear Physics A
Unbound positive-parity states in Li-10 have been populated with a two-proton removal reaction from a 71 MeV/u B-12 beam. The Li-9 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. (C) 2015 Elsevier B.V. All rights reserved.
