CHAPTER XVIII Most Recent Work On Radioactivity Some Properties Of The Alpha And Beta Rays From RADIUM Rutherford 1 has undertaken a new determination of the velocity of the a particle, and of the ratio--for this particle. His method is based upon the well-known principle of measuring the electrical and the magnetic deflections. The magnetic deviation had already been determined with a fair degree of accuracy, but it still remains to measure the electrical deviation more accurately. The difficulty is in obtaining a sufficiently large electrical deflection of the rays. Some interesting facts have, however, already been brought out as the result of this work. It has been recognized that the a rays from radium are complex, consisting of particles projected at different velocities. It will be recalled that a number of the different products formed from radium give off a particles. Indeed, at least five such products exist in radium. The a rays from radium C pass through about twice the thickness of air that the a rays from radium itself do. Thus, each product from radium seems to give off a particles at a certain definite velocity. To measure the velocity of the a particles, those emitted by only one product must be studied at a time. 1 Phil. Mag., io, 163 (1905). The rays given off by the deposit from the emanation, which were really the a particles from radium C, were studied. When the experiments on the electrical deflection of the a particles are completed, Rutherford points out that the ratio--will probably be ascertained with sufficient accuracy to enable us to decide whether or not the a particle is simply a rapidly moving helium ion. An interesting result in connection with the heating effect of radium is referred to in this recent work by Rutherford. I...
