Britannica CD Index Articles Dictionary Help Barkla, Charles Glover (b . June 7, 1877, Widnes, Lancashire, Eng.d. Oct. 23, 1944, Edinburgh), physicist awarded the Nobel Prize for Physics in 1917 for his work on X -ray scattering, which occurs when X-rays pass through a material and are deflected by the atomic electrons. This technique proved to be particularly useful in the study of atomic structures. Educated at Trinity and King's colleges, Cambridge, he joined the faculty of Liverpool University in 1902, moved to the University of London in 1909, and became professor of natural philosophy at the University of Edinburgh in 1913. In 1906 Barkla and C.A. Sadler used X-ray scattering to determine the number of electrons in the carbon atom. At about the same time he was able to polarize X-rays (select X-ray waves that vibrate in the same plane), thus demonstrating that X-rays are transverse waves and hence like other electromagnetic radiations, such as light.

Documentary Biography Charles Glover Barkla was born on June 7, 1877 at Widnes, Lancashire, England, where his father, J.M. Barkla, was Secretary to the Atlas Chemical Company. He was educated at the Liverpool Institute and entered University College, Liverpool, in 1894 to study mathematics and physics, the latter under Oliver Lodge. He graduated with First Class Honours in Physics in 1898 and in the following year he obtained his master's degree. Also in 1899, he was awarded a research scholarship by the Royal Commissioners for the Exhibition of 1851 and he proceeded to Trinity College, Cambridge, to work in the Cavendish Laboratory with J. J. Thomson

He demonstrated that X rays are electromagnetic waves and not particles. Barkla won the 1917 Nobel Prize in physics. Barkla researched the phenomenon of X-ray scattering. When an X-ray beam falls upon a substance, a secondary radiation is emitted. Barkla's research demonstrated that some of the X rays that come back from a material are the original X rays reflected without change, but others (called “characteristic radiation”) are given out by atoms of the material and have different wavelengths from the original radiation. The way in which a solid deflects X rays tells scientists about the size, shape, and arrangement of that solid's molecules. This research laid a foundation for the concept of atomic number. Barkla also showed that secondary radiation of heavy elements has two types of characteristic radiation: a radiation, called K, and a less penetrating radiation, called L . In 1898, Barkla graduated from University College, Liverpool, with a first-class honors degree in physics and went on to earn a master's degree the following year. He then enrolled at Trinity College, Cambridge, but after 18 months transferred to King's College so that he could sing in its renowned choir. Barkla had a marvelous voice, and his solo concerts were well attended.

Encyclopædia Universalis, le portail de la connaissance Accueil Boutique Contact Assistance J'ai oublié mon mot de passe Zone de recherche Saisir un mot clef BARKLA CHARLES GLOVER Charles Glover Barkla naquit à Widnes, dans le Lancashire (Grande-Bretagne) le 7 juin 1877. Après des études à Liverpool, il fit ses premières recherches à Cambridge puis retourna à Liverpool de 1902 à 1909. Il fut alors nommé professeur à l'université de Londres, avant d'occuper la chaire de physique de l'université d'Édimbourg de 1913 jusqu'à sa mort, le 23 octobre 1944 à Édimbourg. C'est à l'étude des rayons X, découverts par Wilhelm Conrad Röntgen, que Barkla a consacré l'essentiel de sa carrière scientifique. Il a découvert que ces rayons peuvent être polarisés, d'où il résulte qu'ils ont bien des points communs avec la lumière. Ses expériences sur leur absorption montrèrent comment on pouvait leur appliquer la théorie quantique. Le rayonnement secondaire induit par l'exposition d'une substance aux rayons X a été, en particulier, le sujet d'études minutieuses. Barkla put déterminer qu'il est composé d'un flux d'électrons et d'un double rayonnement X : l'un de même nature que le rayonnement inc […] … pour nos abonnés, l'article se prolonge sur 1 page…
