Triple differential cross sections for the electron-impact ionization of helium at 102 eV incident energy.
MetadataShow full item record
We examine the time-dependent close-coupling (TDCC) approach to electron-impact singleionization of helium and study the convergence properties of our method. As an example, wecompare our calculations to recent measurements of the triple differential cross sections fromHe after 102 eV electron impact, made for asymmetric electron energies and a variety ofelectron geometries. We find that our calculations compare well to the measurements and toconvergent close-coupling calculations.(Some figures in this article are in colour only in the electronic version)

Rationale, design and methods for a randomised and controlled trial to investigate whether home access to electronic games decreases children's physical activityStraker, Leon; Abbott, R.; Piek, Jan; Pollock, Clare; Davies, P.; Smith, Anne (2009)Background: Many children are reported to have insufficient physical activity (PA) placing them at greater risk of poor health outcomes. Participating in sedentary activities such as playing electronic games is widely ...
To remove or to replace traditional electronic games? A crossover randomised controlled trial on the impact of removing or replacing home access to electronic games on physical activity and sedentary behaviour in children aged 10-12 years.Straker, Leon; Abbott, R.; Smith, Anne (2013)Objective: To evaluate the impact of (1) the removal of home access to traditional electronic games or (2) their replacement with active input electronic games, on daily physical activity and sedentary behaviour in children ...
Effects of home access to active videogames on child self-esteem, enjoyment of physical activity, and anxiety related to electronic games: results from a randomized controlled trialAbbott, R.; Smith, Anne; Howie, Erin; Pollock, Clare; Straker, Leon (2014)Objective: Active-input videogames could provide a useful conduit for increasing physical activity by improving a child’s self-confidence, physical activity enjoyment, and reducing anxiety. Therefore this study evaluated ...
