Phase and group velocities of Rayleigh waves in a spherical, gravitating Earth Periods of spheroidal eigen vibrations, with order of spherical harmonic n20, have been computed for self-gravitating inhomogeneous spheres corresponding to a variety of earth models. The periods are used to deduce phase ...
