The National Institute of Standards and Technology (NIST) database on ionization potentials
for neutral atoms and ions is examined. For each isoelectronic sequence, we construct a …

We show through numerical investigations that the ground-state correlation energies of
atomic ions follow an unexpectedly simple scaling relation, E c≈ Z 4/3 fc (Z/N), where N is …

We study N-electron atoms with nuclear charge Z. It is well known that, in the cationic (Z> N)
large-Z region, the atom behaves as a weakly interacting system. The anionic (Z< N) regime …

In the present thesis, we will focus on a less studied aspect of Thomas-Fermi theory: the
highly non-trivial scaling relations following from it. The main objective of this thesis is to …

La carga eléctrica de los electrones y protones está cuantizada. Como consecuencia, la
carga nuclear, Z, sólo puede tomar valores enteros. Sin embargo, en ocasiones, imaginar Z …

En este trabajo se estima el umbral de carga nuclear,[Z. sub. c], por debajo del cual el
átomo se vuelve inestable. Para ello se utiliza un procedimiento de interpolación …
