Target residue recoil properties in the interaction of 8.0 GeVNe20withTa181

The thick target, thick catcher technique has been applied to determine the average kinematic properties of a number of target-fragmentation products formed in the reaction of 8.0 GeV (400 MeV/A) ${}_{}{}^{20}{}_{}{}^{}\mathrm{Ne}$ with ${}_{}{}^{181}{}_{}{}^{}\mathrm{Ta}$. The forward momentum transferred to the target as a function of product mass is larger than that for the reaction of 25 GeV ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$ or relativistic protons with heavy targets, suggesting that limiting fragmentation has not been achieved in the interaction of 8 GeV ${}_{}{}^{20}{}_{}{}^{}\mathrm{Ne}$ projectiles with a ${}_{}{}^{181}{}_{}{}^{}\mathrm{Ta}$ target.
