Coherence Parameters for Electron Capture in H⁺ + He Collisions

The classical trajectory Monte Carlo method is used to calculate coherence parameters for electron capture to H(n = 2, 3 and 4) in 30 to 250 keV H+ + He collisions. The parameters evaluated are the x- and z-components of the dipole moment (D) and the z-component of the perihelion velocity of the captured electron (L x A). The calculated integral values are found to be in reasonable agreement with available experimental results. Components of the dipole moment and (L x A) were also evaluated as a function of projectile scattering angle. Here, rapid variations of the parameters are observed near the Thomas angle that indicate the transition from the hard, large angle collisions between the projectile and target nucleus to the soft, small angle scattering between the projectile and active electron. © 1994 IOP Publishing Ltd

Women, literacy and health: comparing health and education sectoral approaches in Nepal

Functional adult literacy interventions have been regarded for many decades by policy makers as an effective way of imparting health knowledge. Supported by research on the statistical relationships between women’s literacy rates and health indicators, this dominant policy discourse is based on assumptions that non-literate women lack understanding and confidence, and that formal programmes and institutions constitute the main sites of learning. Proposing a broader conceptualisation of literacy as a social practice and of health as connected with social justice, this article draws on policy analysis and the authors’ earlier research in Nepal to re-examine the relationship between gender, literacy and health. By comparing health and literacy approaches used within the education and health sectors and taking account of new and indigenous informal learning practices, the article points to ways of investigating the complex interaction of factors that influence inequalities in gender and health at community level
