A self-consistent field without exchange has been calculated for doubly ionized chromium in the configuration (3p) ^6 (3d) ^4. All integrations were carried out numerically with the aid of a calculating machine. The difference between the final and semi-final approximations to Z₍, ₋ is nowhere greater than 0. 003.
