Resumen de Elastic scattering of positrons by H2O at low energies
- español
Se analiza una aplicación del principio variacional de Schwinger desde la perspectiva de ondas planas para un conjunto base (Jorge L S Lino, Phys. Scr. 80 (2009) 065303), y sección integral y eficaz diferencial para positrón-H2O en el intervalo de 1-10 eV. Los resultados obtenidos se comparan con los experimentos de Zecca et al (J. Phys. B 39 (2006) 1597) y teóricos Arretche et al (Nucl. Instr. Meth. Phys. B 268 (2010) 178).

We present a study theoretical on elastic positron-H2O collisions. More specifically, integral, and differential cross sections in the 1-10 eV energy range are reported. The calculations were performed using the Schwinger multichannel method with plane waves as a trial basics set (Jorge L S Lino, Phys. Scr. 80 (2009) 065303). The positron-H2O interaction is described using the static plus polarization contributions. Comparison of our calculated results with the recent experimental of Zecca et al (J. PHys. B 39 (2006) 1597) and theoretical results of Arretche et al (Nucl. Instr. Meth. Phys. B 268 (2010) 178) is encouraging.
