Abstract
A device is described by which the stopping power for polonium alpha particles of thin solid or liquid films can be compared with that of gases. An optical system measures film thickness, and the relative stopping power is inferred from the decrease of range which results when a thin film is inserted across a beam of alpha particles. The device has been used with polystyrene and acetylene and a relative stopping power of 0.99±0.02 is observed.
