摘要：

Sum rules for electron-proton total cross sections are deduced from the vanishing of various equal-time commutators, and it is shown how these cross sections determine the (spin-averaged) proton expectation values of all equal-time commutators involving components of the electric current and their time derivatives. Mild restrictions on the asymptotic behavior of electromagnetic form factors are also obtained. © 1969 The American Physical Society.
