Single neutron emission following Li-11 beta-decay Academic Article uri icon


  • The spectrum of neutrons emitted after the -decay of 11Li has been measured with a large time-of-flight array. The spectrum exhibits six peaks corresponding to neutron emission from known states in the 11Be daughter nucleus. The measured branching ratios indicate significant feeding to states over a broad energy range. The energies and parities of the states are in very good agreement with the previous results of the 9Be(t,p) reaction. Comparison of the present results with shell model calculations indicate the effect of the two neutron halo in 11Li. The beta-delayed neutron spectrum of 8He was determined in order to remove contributions from beam contamination. 1997 Elsevier Science B.V.
