Charge Measurements of Stopping High-Z Nuclei (6⩽Z⩽92) in Nuclear Emulsion

The technique of charge determination by measurements of track-width of stopping tracks in nuclear emulsion has been extended to uranium nuclei. The method utilizes the last 1 mm of residual range to estimate mean-track-widths, and has been applied to nuclear beams of Z = 6, 26, 57 and 92. A resolution in charge of σ(Z) = ≲2 units was obtained over the entire interval of charges 6 ⩽ Z ⩽ 92.
