Barkla was born in Widnes, England, to John Martin Barkla, a secretary for the Atlas Chemical Company, and Sarah Glover, daughter of a watchmaker.
Barkla studied at the Liverpool Institute and proceeded to Liverpool University with a County Council Scholarship and a Bibby Scholarship. Barkla initially studied Mathematics but later specialised in Physics under Sir Oliver Lodge. During the absence of Oliver Lodge due to ill health, Barkla replaced him in lectures.[4]
After a year and a half at Trinity College, Cambridge, his love of music led him to transfer to King's College, Cambridge, in order to sing in their chapel choir. Barkla's voice was of remarkable beauty and his solo performances were always fully attended.[6] He completed his Bachelor of Arts degree in 1903, and then his Master of Arts degree in 1907.[7] He married Mary Esther Cowell in the same year,[8] with whom he had two sons and one daughter.
Barkla made significant progress in developing and refining the laws of X-ray scattering, X-ray spectroscopy, the principles governing the transmission of X-rays through matter, and especially the principles of the excitation of secondary X-rays. For his discovery of the characteristic X-rays of elements, Barkla was awarded the Nobel Prize in Physics in 1917. He was also awarded the Hughes Medal of the British Royal Society that same year.
Barkla proposed the J-phenomenon as a hypothetical form of X-ray behaviour similar to X-ray fluorescence but other scientists were not persuaded that this was a different mechanism from other known effects such as Compton scattering and so the theory was not successful.[9][10]
From 1922 to 1938 he lived at Hermitage of Braid in south-west Edinburgh.[11]
He died in Edinburgh on 23 October 1944.
Personal lifeedit
Plaque to C G Barkla, Hermitage of BraidHermitage of Braid, Edinburgh
A religious man, Barkla was a Methodist and considered his work to be "part of the quest for God, the Creator".[12][13][14]
A plaque exists on Barkla's house at Hermitage of Braid in Edinburgh. A commemorative plaque has been installed in the vicinity of the Canongate, near the Faculty of Education Buildings, at the University of Edinburgh. Additionally, a lecture theatre at the University of Liverpool's Physics department, as well as a Biophysics laboratory in the Biological science department,[15] are named after him. In 2012 a gritter in Barkla's home town of Widnes was named in his honour, following a competition run by the local newspaper.[16] In Widnes they have a Retirement housing Complex named Barkla Fields after Charles.
