Annotation
A method is proposed for precise calculation of the dimensionally regularized apex type Feynman diagrams. This metod is used to find expressions for a class of massless vertex integrals which expand the number of precisely calculable Feynman diagram in the quantum field theory and which are of interest for calculations in gage theories and in studying processes involving participation of elementary particles at high energies.
