Alpha particle types: eventually named alpha, beta, and gamma by Rutherford, based on penetration of objects and deflection by a magnetic field. Alpha rays were defined by Rutherford as those having the lowest penetration of ordinary objects. Rutherford's work also included measurements of the ratio of an alpha particle's mass to its charge, which led him to the hypothesis that alpha particles were doubly charged helium ions (later shown to be bare helium nuclei). In 1907, Ernest Rutherford and Thomas Royds finally proved that alpha particles were indeed helium ions. To do this they allowed alpha particles to penetrate a very thin
Production and Decay of Strange Particles Production and Decay of Strange Particles "Production and Decay of Strange Particles" is an episode of the original "The Outer Limits" television show. It first aired on 20 April 1964, during the first season. The plot involves workers at a nuclear research plant wearing radiation suits, who are taken over by some odd glowing substance that fills their suits and causes them to act as puppets of the force inside. Mentioned in the episode are many modern physics concepts such as neutrinos, antimatter, quasi-stellar objects (at that time just discovered and perhaps mentioned here in TV fiction for the first
