This article is superceded by the subsequent article from the same authors: "Discrete Excitation Spectrum of a Classical Harmonic Oscillator in Zero-Point Radiation," published in Foundations of Physics, March 2015, Volume 45, Issue 3, pp 333-353. doi: 10.1007/s10701-015-9866-9 Available in the UNL DigitalCommons at


We report that upon excitation by a single pulse, the classical harmonic oscillator immersed in classical electromagnetic zero-point radiation, as described by random electrodynamics, exhibits a quantized excitation spectrum in agreement to that of the quantum harmonic oscillator. This numerical result is interesting in view of the generally accepted idea that classical theories do not support quantized energy spectra.
