• In place of the usual method of grain counting in which all the silvergrains in a certain length from the end of a track are counted, a new method has been developed by counting only the grains excepting those in the last fifty microns of the track, since near the end of a track the apparent number of grains is not proportional to the energy loss. The ratio of the average number of grains in equal lengths of track-segments of deuterons and protons was found to be as high as 1.28±0.03, in contrast to the values ranging from 1.10 to 1.17 hitherto reported. The method has been applied to the discrimination of photodeuterons from photoprotons.
