SEMANA IV
	Redes de Difração, Difração por Abertura Circular e Difração de Raios-X Sir William Henry Bragg (1862-1942) and Sir William Lawrence Bragg (1890-1971), father and son, were intensely interested in the X-ray diffraction work done by von Laue. They used his discovery to                    study crystal structure and developed the X-ray spectrometer. Their Nobel prize in physics followed                    von Laue's by a year, in 1915. The Royal Institute of Chemistry stamp shows the crystal structure of                    salt, as determined by WLB, and used by WHB to determine X-ray wavelengths.
