| alpha r.’s |
high-speed helium nuclei which have been ejected from radioactive substances. Owing to their high velocity (one tenth that of light) their kinetic energy is so great that a single alpha particle produces a microscopic flash of light when it hits a spinthariscope; when it hits another atom (as of nitrogen) it may cause it to disintegrate.
