With use of the Deser-Gilbert-Sudarshan representation, the connected diagonal matrix elements of current anticummutators taken between two stable one-particle states on the null plane are derived. It is shown that the assumption necessary to restrict to the null plane in this case is equivalent to that in case of current commutators. Following Dicus, Jackiw, and Teplitz, we derive sum rules from these anticommutators. We investigate some of them, and obtain, in the case of pion-nucleon or kaon-nucleon scattering, the quantitative relation between the sea-quark distribution in the nucleon and the Pomeron.
