We present an interpretation of recent experimental results on nucleon-anti-nucleon annihilation reactions of the type N{bar N} {yields} {pi}X, which have yielded evidence for a new tensor meson AX (here called X{sub 2}) with J{pi}{sup C}(I{sup G}) = 2{sup ++}(0{sup +}). The branching ratios for producing X{sub 2} from N{bar N} atomic states of orbital angular momentum L = 0,1, as well as its preference for decay into {rho}{rho} and {pi}{pi} rather than K{bar K} channels, are consistent with the identifications of X{sub 2} as a {sup 13}P{sub 2}{minus}{sup 13}F{sub 2} bound state of the N{bar N} potential. We suggest further key test of this interpretation. 21 refs.
