Resonance enhanced multiphoton ionization photoelectron spectroscopy on nano- and picosecond timescales of Rydberg states of methyl iodide
Four-photon excitation of autoionizing states of Ar, Kr and Xe between the E2PC3C\C2 and E2PC1C\C2 ionic limits
A (3+1) resonance enhanced multiphoton ionization study of the C 1S+ and E 1P states of CO: polarization dependence used to probe electronic excitation routes and electronic character
The three-photon excitations of the C 1 + and E 1 states have been investigated with resonance enhanced multiphoton ionization spectroscopy as a function of the polarization of the excitation light. From the observed polarization dependence the contributions of the various excitation routes have been determined, and the electronic character of these states has been analyzed. The results indicate that the v=0 and 1 vibrational levels of the E 1 state have slightly different electronic characters.

The genus Boccardia (Polychaeta: Spionidae) associated with mollusc shells on the south coast of South Africa
Three species of Boccardia (B. polybranchia, B. pseudonatrix and B. proboscidea) were associated with mollusc shells on the south and south-east coasts of South Africa. Boccardia polybranchia was widely distributed along the coast and falls within the known distribution range of this species. Comparisons with material from other, international, locations showed that some specimens have been misidentified. No characters could be found to characterize distinct species for different regions within the range of B. polybranchia, as currently recognized. Boccardia pseudonatrix was found only at the most eastern site, increasing its known distribution range. Boccardia proboscidea, a non-indigenous species, was found only on abalone farms and was most abundant in the west
