| Title | Gray, Joseph Alexander: certificate of election to the Royal Society |
| Citation | Distinguished for his researches in radio-activity, particularly on the properties of beta and gamma rays. He was the first to prove that beta rays excite secondary gamma rays and he showed that gamma rays must be of the same nature as X-rays. In 1913 he deduced from experiments that the scattering of gamma rays (and later also of X-rays) involved a change of frequency depending on the angle of scattering, and thus clearly foreshadowed what is now known as the Compton effect. From 1925 onwards he has contributed much to our knowledge of the scattering and absorption of gamma and X-rays. His work is characterised throughout by marked originality of outlook and by the simplicity of his experimental methods. |
