Abstract: Experimental ranges are determined for the passage of 238U ion in Tantalum for energies up to ~3.8 GeV utilizing a versatile nuclear-track technique. The Solid State Nuclear Track Detector (SSNTD) utilized in the present examination is Polyallyl Diglycol Carbonate, industrially known as CR-39. The exploratory information are contrasted and comparing hypothetical qualities acquired from SRIM, conditions of Mukherji et al, the information tables of Hubert et al and of that of Northcliff and Schilling.
