| Abstract: | Taking ReM 1? as a parameter ReE 0+, ReE 1+ and ReM 1+ are determined by a phenomenological analysis using the measurements ofHitzeroth andGovorkov et al. Taking for ReM 1? the present theoretical values ReE 1+ turns out to be negative. ¦ReE 0+¦ is smaller than former theoretical calculations suggest. The influence of the imaginary parts and of the higher multipoles is discussed. |
