M(γ): From γ(θ) in (n,n’γ) and (9Be,9Be’γ).
   1635.76   1199.2M(γ): Isotropic γ(θ) to 2+ in (n,n’γ) consistent with E2 from 0+ initial level.

M(γ): ΔJ=0 dipole from excit. function and γ(θ) in (n,n’γ), electric character inferred from likely parity deduced for initial state. In (9Be,9Be’γ) data, an opposite sign for A2 is reported, and hence, ΔJ=1 dipole, which is inconsistent with (n,n’γ). The evidence more strongly supports the former assignment.
