Description
Two-photon decays of a tensor D*D* molecule are studied and the suggested approach is applied to the X(3915) charmoniumlike state under the assumption of the latter being a 2++ molecule - a spin partner of the X(3872). It is argued that the existing experimental data disfavour such an identification of this state. Therefore, it is suggested that either the X(3915) has a different exotic nature or it has to be identified as a scalar.
