Abstract
In this work we calculate two two-loop massless Feynman integrals pert aining to self-energy diagrams using NDIM (Negative Dimensional Integr ation Method). We show that the answer we get is 36-fold degenerate. W e then consider special cases oi exponents for propagators and the out coming results compared with known ones obtained via traditional metho ds.
