Effects of the nonsymmetric gravitation theory and radial perturbations of the lunar orbit

The predictions of the nonsymmetric gravitation theory of Moffat for the radial perturbations of the lunar orbit are computed. An effect is found but, given the accuracy of Lunar Laser Ranging Experiment data, it is not likely to be detected, even if the accuracy of the data is improved by a factor of 100. The calculation is done in a post-Newtonian coordinate frame. The transformation to an Earth-based normal coordinate frame is shown not to affect the results.
