tric Deviation of a Rays. The a rays were early distinguished from-Hye/rogtn the ^ rays by the fact thatthey were much less penetratingthan the ^ rays and also thatthey were apparently not devi-able by a magnetic field. Theirimportance was not at firstrecognized and their true na-ture was not… … RADIUM. ^ 655 positively charged particles emitted with great velocity. Totest this the crucial experiment, of course, was to try to bendthe rays by a magnetic field. Rutherford was the first to succeedin doing this. His apparatus is shown diagrammatically in Fig.510. Unless the radiation is very…
