The method for obtaiming fixed-t sum rules using unsubtracted dispersion relations or Regge asymptotic behavior is due toV. De Alfaro, S. Fubini, G. Rossetti andG. Furlan:Phys. Lett.,21, 576 (1966); andL. D. Soloviev: Dubna preprint (1965). There are many other strong-interaction sum rules from asymptotic behavior which have been discussed previously. SeeM. L. Goldberger, H. Miyazawa andR. Oehme:Phys. Rev.,99, 986 (1955);G. F. Chew, M. L. Goldberger, F. E. Low andY. Nambu:Phys. Rev.,103, 1343 (1957);R. G. Sachs:Phys. Rev.,126, 2256 (1962);A. P.
