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.
