          Abstract

          The alignment parameter A20 of the L3-subshell of Ce, Nd, Eu, Dy, and Yb has been calculated by measuring the anisotropic emission of the L¡ X-ray line induced by 12C ion impact at 9 MeV bombardment energy. A new Coster-Kronig transition probabilities database is used, as well as more recent theories for ionization cross sections. These experimental results are in better agreement with the theory than previously published data.

          Midiendo la emisión anisotrópica de rayos X de la línea Ll inducidos por impacto de iones de 12C a 9 MeV, se calculó el parámetro de alineación A20 para la subcapa L3 de los elementos Ce, Nd, Eu, Dy e Yb. Se utilizó una nueva base de datos para obtener las probabilidades de transiciones Coster-Kronig así como teorías más recientes para calcular las secciones eficaces de ionización. Se observa que los resultados experimentales obtenidos en este trabajo concuerdan mejor con la teoría en comparación a resultados obtenidos con anterioridad.
