Abstract

A recent paper [Phys. Rev. C 83, 057304 (2011)] used knockout from ¹²Be to populate two states near 3.9 MeV in ¹¹Be and observed their neutron decay—but treated the two as a single state. The authors used a branching ratio for the upper state from an experiment that also did not separate the two states. Thus, their energy for ¹¹Be(3.96 MeV) and the spectroscopic factor connecting it to ¹²Be(gs) are questionable.
