Reaction mechanism dependence of the population and decay of 10he
The two-neutron unbound nucleus 10He was studied with a 44 MeV/u 11Li beam and a 47 MeV/u 13B beam. Neutrons were measured in coincidence with 8He fragments, and the two-body and three-body decay energies were reconstructed using invariant mass spectroscopy. Due to low statistics and large decay contributions from the population of 9He, energies of resonant states in 10He could not be extracted from the 13B beam. The 11Li beam data could be described with a correlated background model, implying that the measured spectra are strongly influenced by the initial halo configuration of 11Li. In addition, from comparisons with previous data a target dependence of the data is suggested.
