Abstract
The calculation method of the hadron-interaction vertex with constant external fields in QCD sum rules is discussed. The representation of t he polarization operator in terms of physical-state contributions is c onsidered, and the most suitable form of this representation is sugges ted. Estimates of uncertainties in the previous calculations of hadron -interaction vertices with external fields are given.
