Is there a low-lying 1(-) state in He-10?
Artikel i vetenskaplig tidskrift, 2013
In a recent paper by S.I. Sidorchuk et al., Phys. Rev. Lett. 108 (2012) 202502, angular correlations in the decay of He-10 were interpreted as a coherent superposition of a 0(+), 1(-) and 2(+) states. It was concluded that it is the 1- state that dominates in the energy region 4.5-6 MeV. It is here demonstrated here that the experimental data might be understood without assuming the presence of a low-lying 1(-) state.
