Text: "Gravitation and antigravitation." The localizability of gravitational energy is re-examined. It is concluded that there is no unequivocal justification for its exclusion as a source term in Einstein's field equation. Calculations are presented to show how the results of general relativity theory should be corrected if gravitational energy is localizable and is itself a source of gravitation. The possibility of anti-gravitational systems is demonstrated. Proceedings of the West Virginia Academy of Science. 52(2), 1980. p. 106-118.
