Hace cuarenta años una versión del modelo de carga efectiva se deshizo de la afirmación de que el hidrógeno interactúa como protón en la materia para tener en cuenta para las relaciones de stoping power entre átomos de Helio e Hidrógeno en metales simples. En este trabajo se muestra cómo las fracciones de carga efectiva de Helio y otros elementos ligeros relevantes en aluminio también obedecen la curva universal de ionización de Brandt. Se realiza la comparación en el subsiguiente modelo por Brandt-Kitagawa. El tema sigue en discusión.

Forty years ago a version of the effective-charge model got rid of the statement that hydrogen interacts as a proton in matter, to account for the stopping power ratios between helium and hydrogen atoms in simple metals. In this paper it is shown how the effective-charge fractions of helium and other relevant light elements in aluminium also obey the Brandt's universal ionization curve. Comparison is done to the succeeding model by Brandt-Kitagawa. The subject keeps on in discussion.
