The small and subtle effects of electron correlation in the Rydberg‐like 3 1 D and 3 3 D states of the helium‐like ions are studied using very accurate explicitly correlated wave functions. In particular, the effects of electron correlation on one‐electron densities, probability distributions for the interelectronic distance, and their moments are examined with the help of density and Coulomb holes. Statistical electron correlation is examined with radial and angular correlation coefficients. The different methods of analysis provide complementary insight. © 1993 John Wiley & Sons, Inc.
