Nature of the E_n = 1.24 MeV state in ¹²Be

Abstract.

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 $2^{+}$, rather than the previously suggested ($2^{-}$, ( $1^{-}$)). 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%.
