The electronic Raman transition between the lower 1s(p{sub 3/2}) and the higher 1s(p{sub 1/2}) state of a hole bound to a boron acceptor in diamond, examined under the high resolution of a Fabry-Perot interferometer, reveals a doublet separated by (0.81{+-}0.15) cm{sup -1} , indicative of a spontaneous symmetry breaking of the fourfold degenerate ground state. The direct transition between the levels into which 1s(p{sub 3/2}) :{gamma}{sub 8} resolves, with a Raman shift of (0.80{+-}0.04) cm{sup -1} , provides a remarkable confirmation of the symmetry lowering shown to arise from a static Jahn-Teller distortion.
