Magnon Raman spectra in the half-filled two-dimensional Hubbard model are calculated by using the exact diagonalization of a X/-8 x v'-8 lattice. Theoretical results of the peak positions and relative intensities of the B~, A~ and B 2 spectra agree with the observed ones. The frequency dependence of
