He evolved the laws of X-ray scattering and the laws governing the transmission of X rays through matter and excitation of secondary rays. For his discovery of the characteristic X-rays of elements he received the 1917Nobel Prize in Physics. He was awarded the Royal Society's Hughes Medal that same year.

CharlesBarkla was one of the first scientists to help reveal the true nature of X-rays and, through later applications of his findings, the nature of the atom.
While using various samples of gases to scatter his X-rays, he noticed that different gases affected the intensity of the rays differently, and that the intensity of change was proportional to the gas's position on the periodic table of elements (and, thus, proportional to its atomic weight).
CharlesGloverBarkla (June 7, 1877 – October 23, 1944) was a British physicist.
Barkla's first researches concerned the velocity of electric waves along wires but in 1902 he commenced his investigations on Röntgen radiation which were to occupy almost his whole life.
Barkla made valuable contributions to present knowledge on the absorption and photographic action of X-rays and his later work demonstrated the relation between the characteristic X-radiation and the corpuscular radiation accompanying it.
CharlesGloverBarkla married Mary Esther, the eldest daughter of John T. Cowell of Douglas, Receiver-General of the Isle of Man, in 1907.
