Partitioning technique procedure revisited II: Application to the Stark and Zeeman problems in light atoms

Abstract

We show that the modified partitioning procedure can be applied to study the spherical and nonspherical Stark effect in the hydrogen atom and the spherical quadratic Zeeman effect in H-, the helium atom and He‐like ions: Li++, Be++, etc. We present ground‐state energy values for γ (in a.u.) in the interval 0.001 ≤ λ ≤ 0.2 (a.u.= 5.142·109 volts/cm) and for magnetic field γ (in a.u.) in the interval 0.1 ≤ γ ≤ 1.0 (a.u. = 2.353·109 gauss). We compare our results to values available in the literature; they are, in general, better than those obtained by other methods.
