Abstract
We report an application of the Schwinger variational principle with plane waves as a trial basis set [J.L.S. Lino, M.A.P. Lima, Braz. J. Phys. 32, 432 (2000)]. Differential cross sections are obtained for electron-NH3 collisions from 8.5 to 30 eV. Differential cross sections are found to be in reasonable agreement with existing measurements.
Keywords: Elastic scattering of electrons; molecular excitation.
Resumen
Se analiza una aplicación del principio variacional de Schwinger desde la perspectiva de ondas planas para un conjunto base [J.L.S. Lino, M.A.P. Lima, Braz. J. Phys. 32, 432 (2000)]. El propósito de este trabajo es mostrar la secciones eficaces diferenciales para las colisiones electron-NH3 entre 8.5 - 30 eV. Los resultados obtenidos se comparan con los experimentos.
Descriptores: Retrodispersión elástica de electrones; excitación molecular.
