Benchmark Calculations of Electron-Impact Differential Cross Sections
MetadataShow full item record
The Calculation of electron-atom excitation and ionization cross section is considered in both the non-relativistic and relativesic scattering theory. We consider electron collisions with H. He. Cs and Hg. differential crosssections for elastic scattering and Ionization are presented.

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 ...
