Abstract
Two-photon transitions from the Eu I ground state 4f 7 6s 2 a 8 S 7/2 to odd levels with alsoJ=7/2 in the energy range of 34,000 – 36,700 cm−1 were analysed due to their scalar and quadrupolar contributions. Their ratioR (g, e) were determined experimentally. In most cases the quadrupole contributions are dominant, i.e. 0<R (g, e) exp <20·10−3. In the two-photon transition to the level 4f 7 5d 2 8 F 7/2 the ratio is remarkably strong:R (g, e) exp =134 (4)·10−3. A theoretical estimation ofR (g, e) is not yet satisfying, due to strong configuration mixing in Eu.
