I suggest that a new state (Phys. Rev. C 90, 024309 (2014)) observed in 12Be, with a neutron decay energy of 1243keV, is likely to be , rather than the previously suggested (
, (
)). Primary p-wave decay is then to the first excited state of 11Be, but a possible d-wave g.s. branch could be as large as about 10%.
