“…It shows that the charge resolution is remarkably high in this type of measurement,when a straightforward sum of the measured widths is used as the charge parameter. The resolutions are nearly equal to those obtained in photometric measurements in the same emulsions in the same range intervals [2]. It must, however, be stressed that the high resolution can only be reached when possible changes in the criteria of measurement can be controlled and corrections can be applied.…”

By means of width measurements with a filar micrometer the charges of nuclei stopping in nuclear emulsion can be determined. The method of measurement is tested on tracks of 100 stopping cosmic ray nuclei of known nuclear charge Z = 5-26 in G5-emulsion in the residual range interval 0 ⩽ R ⩾ 400 μm. The widths are measured according to a special procedure of measurement.The study shows that it is possible to apply the method of identification on low energy heavy nuclei stopping in the emulsion. The method is a valuable complement to photometric methods at residual track ranges less than 400 μm and is to advantage applicable to fragments emitted in nucleus-nucleus interactions in emulsion at least if the dip angles of the fragments are less than about 35°.
