Abstract：
It is shown that the Pomeron could be regarded as a Reggeized Tensor Glueball with a trajectory of ap(t)=1.08+0.2GeV-2t. Under mis theory, the total cross section measured for pp elastic scattering at high energies is reproduced successfully. The best fits to experimental data lead to a Γ_ξ→pp=9±3MeV and Γ_ξ>50MeV J=4 for spin of the tensor glueball m_ξ(2230) is precluded.
