The Nature of X-rays


IN a paper published in the October number of the Philosophical Magazine (pp. 429–449), Prof. Bragg, after discussing the properties of various electric radiations, arrives at the conclusion that although a beam of X-rays contains some ether pulses, these may not after all constitute the bulk of Röntgen radiation. In place of the usually accepted theory, he proposes the hypothesis that these rays consist mainly of “neutral pairs” (consisting of a positive and a negative particle) each revolving in a plane containing its direction of translatory motion. This, he considers, affords an easier explanation of the properties of the rays, and is not improbable a priori.
