Tidal Deformation of the Moon

Tides on the surface of the Moon are investigated. The tidal potential, gravity and displacements on the surface of the Moon are expanded in harmonics depending on general forms of the lunar motion, which would accept the orbital evolution. These are expressed in numerical formulas more exactly for uses in correction for precise determination of the lunar motions and for possible observations of the tides of the Moon. Love numbers are computed for some expected models of the lunar interior. Possibilities are shown to discriminate the core effect in the tidal observations.
