    S-wave model in electron-atom collisions

    No full text
    This thesis discusses the theory and presents the numerical solution of the S-wave models of electron-hydrogen and electron-helium scattering. The Convergent Close-Coupling (CCC) method is used to obtain the numerical results. The focus within the electron-hydrogen S-wave model is to investigate cross section results for scattering from excited states; in particular, the elastic free-free transitions. These contain a divergent potential matrix element as the first term. The investigation of the electron-helium S-wave model is split into two sections, firstly applying the Frozen-Core approximation and then relaxing this approximation. This includes the first accurate ab initio calculation of double-excitation of helium

    Hypocreadium cavum Bray & Cribb, 1996 (Figure 1) Host: Abalistes stellatus (Anonymous), Balistidae, starry triggerfish. Site: Intestine. Locality: Swain Reefs, southern Great Barrier Reef, off Queensland, Australia (21 ° 53 ’S, 152 ° 21 ’E, Feb. 2001). Prevalence: 1 of 1. Voucher specimens: QM G 230517 – 230519, BMNH 2009.2.12.47– 48. Remarks: These specimens agree well with those described by Bray & Cribb (1996) from the same host species from Heron Island (see Table 1). This is the first record of this parasite from this locality. Machida & Kuramochi (1999) reported, but did not illustrate, this species from the balistid the yellow-margined triggerfish, Pseudobalistes flavimarginatus (Rüppell), from Palau in Micronesia. These authors point out that in their specimens the ventral sucker is larger, the eggs are smaller, the ovary is more or less post-testicular and the massive development of gland-cells around the cirrus-sac is absent. In our new specimens, the ventral sucker is distinctly smaller than in the specimens from P. flavimarginatus, no eggs were seen, the ovary is intertesticular, there are numerous gland-cells around the cirrus-sac and the genital pore is always just postbifurcal. Bray & Cribb (2002) also reported this species from the masked triggerfish, Sufflamen fraenatum (Latreille), from Heron Island. They found the measurements to agree with those of Bray & Cribb (1996). There remains some substantial doubt as to the status of the forms from Palau.Published as part of Bray, Rodney A., Cribb, Thomas H. & Justine, Jean-Lou, 2009, New observations on the genus Hypocreadium Ozaki, 1936 (Digenea: Lepocreadiidae) in the Indo-West Pacific region, including the description of one new species, pp. 22-40 in Zootaxa 2110 on page 23, DOI: 10.5281/zenodo.18786
