Majorana: From Atomic and Molecular, to Nuclear Physics

  title={Majorana: From Atomic and Molecular, to Nuclear Physics},
  author={Renato Pucci and Giuseppe G. N. Angilella},
  journal={Foundations of Physics},
In the centennial of Ettore Majorana’s birth (1906–1938?), we re-examine some aspects of his fundamental scientific production in atomic and molecular physics, including a not well known short communication. There, Majorana critically discusses Fermi’s solution of the celebrated Thomas–Fermi equation for electron screening in atoms and positive ions. We argue that some of Majorana’s seminal contributions in molecular physics already prelude to the idea of exchange interactions (or Heisenberg… 

Ettore Majorana’s Early Scientific Production

Among Ettore Majorana’s (1906–1938) earliest works, there is a brief memory on the Thomas–Fermi model , and a paper on the chemical bond in the helium molecular ion. Here, we emphasize Majorana’s

Majorana Solutions to the Two-Electron Problem

The two-electron atom is the simplest nontrivial quantum system not amenable to exact solutions. Today, its relevance in the development of quantum mechanics and its pedagogical value within the

From Majorana Theory of Atomic Autoionization to Feshbach Resonances in High Temperature Superconductors

The Ettore Majorana paper “Theory of incomplete P′ triplets,” published in 1931, focuses on the role of selection rules for the non-radiative decay of two electron excitations in atomic spectra,

From the Majorana theory of incomplete P ’ triplet to Feshbach shape resonances

The Ettore Majorana paper “Theory of incomplete P' triplets”, published in 1931, focuses on the role of selection rules for the non-radiative decay of two electron excitations in atomic spectra,

Majorana, Pauling and the quantum theory of the chemical bond

Nonlocal electrodynamics is a formalism developed to include nonlocal effects in the measurement process in order to account for the impossibility of instantaneous measurement of physical fields.



Again on Majorana and the Thomas-Fermi model: a comment to physics/0511222

We comment on a recent paper announcing the discovery of a previously unknown publication of Ettore Majorana on the Thomas-Fermi atomic model. In pointing out that such a publication was not written


Ettore Majorana proposed an important improvement to the ThomasFermi statistical model for atoms, with a communication at the general meeting of the Italian Physical Society, held in Rome, on

Theoretical Nuclear Physics

A semi-empirical basis is used to describe and correlate the known nuclear properties including the theoretical concepts, methods, and considerations which have been devised in order to interpret the

Catalog of the scientific manuscripts left by Ettore Majorana (with a Recollection of E.Majorana, sixty years after his disappearance)

Ettore Majorana, perhaps the greatest Italian theoretical physicist of this century (Enrico Fermi compared him to Galilei and Newton), disappeared misteriously from Naples in 1938, when he was 31. In

The quantum theory of the electron allows states of negative kinetic energy as well as the usual states of positive kinetic energy and also allows transitions from one kind of state to the other. Now

The Normal State of the Helium Molecule-Ions He 2 + and He 2 ++

With the use of wave functions constructed from hydrogen-like single-electron functions with an effective nuclear charge Z, the application of the variation method of treating the wave equation for

Possible Existence of a Neutron

IT has been shown by Bothe and others that beryllium when bombarded by α-particles of polonium emits a radiation of great penetrating power, which has an absorption coefficient in lead of about 0.3

Some moments of radial electron density in closed‐shell atoms and their atomic scattering factors

The scattering factor f(K) for x rays from atomic ions with closed shells can be written in terms of the radial electron density D(r) = 4πr2ρ(r), with ρ(r) the electron density. The small K expansion
