Mechanisms of one-electron capture by slow He2+, C4+ and O6+ ions in collisions with CH4

Translational energy spectroscopy (TES) has been used to study one-electron capture by He2+, C4+, and O6+ ions in collisions with CH4 within the range 200 - 2000 eV amu—1. In each case the main collisions mechanisms and product channels have been identified. The measurements reveal significant differences in the way the dissociative and non-dissociative mechanisms contribute to electron capture. However, in all cases, the highly selective nature of the charge transfer process is confirmed in spite of the wide range of energy defects associated with possible product channels.

Ionization of Helium and Argon by Very Slow Antiproton Impact

The total cross sections for single ionization of helium and single and double ionization of argon by antiproton impact have been measured in the kinetic energy range from 3 to 25 jeVusing a new technique for the creation of intense slow antiproton beams. The new data provide benchmark results for the development of advanced descriptions of atomic collisions and we show that they can be used to judge, for the first time, the validity of many recent theories.

‘Glimpses into the unmentionable: Montserrat, tourism and anthropological readings of “subordinate exotic” and “comic exotic” travel writing’

This article explores the relationship between anthropology and identity through the process of travel writing and reading. Specifically, the article examines a range of travel writing about the British Caribbean colony Montserrat to read into the culture of the writer. These deconstructive ‘glimpses into the unmentionable’ reveal an implicit racism. The travel writing texts are also found to divide into two types of representation – the ‘subordinate exotic’ and the ‘comic exotic’.
