Abstract
A statistical study has been made of the grain-spacing of alpha-ray, deuteron and proton tracks in an Ilford emulsion with standardized processing and viewing technique. The alpha-rays were from ThC and ThC' and the deuterons and protons from cyclotrons. A theoretical explanation of the difference in grain spacing is given and some applications of the technique in the study of cosmic rays and nuclear research.
