Formation of tracks of fast heavy ions in nuclear emulsion
A detailed study of the tracks of fast, heavy ions in an electronsensitive nuclear emulsion of type Ilford G5 was carried out. Using a nuclear track photometer with a narrow slit transverse absorption profiles on 27 tracks of nuclei with charge numbers were registered. The charges of the heavy nuclei, emanating from the cosmic radiation, were determined earlier by photometric methods. Theoretical track profiles were computed from the distribution of energy dose around the path of a passing ion. This dose distribution was evaluated according to the delta-ray theory of track structure developed by Katz and co-workers. Utilizing a parameter optimization algorithm, the calculated profiles were fitted to the experimental data. From this comparison one can conclude that a reasonable agreement between experimental and calculated profiles can be obtained if one can adequately compensate for the backscattered light in the emulsion.
