A Simultaneous Discovery: The Case of Johannes Stark and Antonino Lo Surdo

  title={A Simultaneous Discovery: The Case of Johannes Stark and Antonino Lo Surdo},
  author={Matteo Leone and A. Paoletti and Nadia Robotti},
  journal={Physics in Perspective},
In 1913 the German physicist Johannes Stark (1874–1957) and the Italian physicist Antonino Lo Surdo (1880–1949)discovered virtually simultaneously and independently that hydrogen spectral lines are split into components by an external electric field. Both of their discoveries ensued from studies on the same phenomenon, the Doppler effect in canal rays, but they arose in different theoretical contexts. Stark had been working within the context of the emerging quantum theory, following a research… 

The discovery of the Stark effect and its early theoretical explanations

After Pieter Zeeman had discovered in the fall of 1896 that an external magnetic field causes spectral lines to split in several components,1 the logical next step was to investigate whether an

How Sommerfeld extended Bohr’s model of the atom (1913–1916)

Sommerfeld’s extension of Bohr’s atomic model was motivated by the quest for a theory of the Zeeman and Stark effects. The crucial idea was that a spectral line is made up of coinciding frequencies

The Stark effect in the Bohr-Sommerfeld theory and in Schrödinger's wave mechanics

The explanation of the first-order Stark effect in hydrogen by Epstein and Schwarzschild in 1916 was seen as a great success for the old quantum theory. Yet, it also revealed some serious limitations

Experiment and theory: the case of the Doppler effect for photons

In 1907, Einstein suggested an experiment with flying atoms for corroborating time dilation. In that paper, the flying atom was conceived as a flying clock: the reference to the Doppler effect was

Atoms and Molecules Interacting with Light: Atomic Physics for the Laser Era

This in-depth textbook with a focus on atom-light interactions prepares students for research in a fast-growing and dynamic field. Intended to accompany the laser-induced revolution in atomic

Ionisation mit Dissoziation von H2 und Doppelionisation von Xenon in ultrakurzen, kombinierten XUV- und IR-Laserpulsen

Two light sources have been developed that employ the generation of high harmonics (HHG) of the fundamental infra-red (IR) light wave of ultra-short Ti:Saphire laser pulses by a non-linear process in

Exploiting single-ion anisotropy in the design of f-element single-molecule magnets

Scientists have long employed lanthanide elements in the design of materials with extraordinary magnetic properties, including the strongest magnets known, SmCo5 and Nd2Fe14B. The properties of these

Enrico Fermi and the Old Quantum Physics

We outline Fermi's early attitude towards old quantum physics. We sketch out the context from which his interest for quantum physics arose, and we deal with his work on quantum statistics. We also go

Non-Hermitian Hamiltonians with real eigenvalues coupled to electric fields: From the time-independent to the time-dependent quantum mechanical formulation

We provide a reviewlike introduction to the quantum mechanical formalism related to non-Hermitian Hamiltonian systems with real eigenvalues. Starting with the time-independent framework, we explain

Five ways to the nonresonant dynamic Stark effect

The dynamic Stark effect is the quasistatic shift in energy levels due to the application of optical fields. The effect is in many ways similar to the static Stark effect. However, the dynamic Stark



The genesis of quantum theory (1899-1913)

Reviewing the German edition of this book in Physics Today, the physicist Ira M. Freeman writes as follows:"Professor Hermann's book makes it apparent that the history of the early years of quantum

The Constitution of Atoms and Molecules

DR. VAN DEN BROEK'S letter (NATURE, May 7, p. 241) contains one or two misapprehensions of the views put forward in my paper (Phil. Mag., April, 1914), and I shall accordingly endeavour to make my

Observation of the Separation of Spectral Lines by an Electric Field

THE effect of the electric field upon spectral lines is a problem which has caused much discussion without being solved by experiment until to-day. Applying a very intense electric field in an

Enrico Fermi, Physicist

Student, collaborator and lifelong friend of Enrico Fermi, Emilio Segrh presents a rich, well-rounded portrait of the scientist, his methods, intellectual history, and achievements. Explaining in

Atomic Models and X-Ray Spectra

IN his letter to NATURE of January 1 on “Atomic Models and X-Ray Spectra,” Dr. F. A. Lindemann deals with the approximate agreement between the recent experiments of Mr. H. G. J. Moseley on “The
