We prove the following vanishing theorem. Let M be an irreducible symmetric space ofnoncompact type whose dimension exceeds 2 and M ≠ S0(2,2)/S0(2) × SO(2). Let π: → M beany vector bundle. Then any E-valued L~2 harmonic 1-form over M vanishes. In particular we get thevanishing theorem for harmonic maps from irreducible symmetric spaces of noncompact type.
