Abstract

The cross section for the ${}^{12}C$ $(^{139}$ La,X $)^{11}$ C reaction was measured using 1.26-GeV/nucleon ${}^{139}{La}$ ions. Annihilation radiation from the decay of ${}^{11}C$ was counted using a large volume NaI(Tl) detector. The resulting cross section for ${}^{139}{La}$ was 147.9±2.0 mb. The results are compared with similar measurements using relativistic ${}^{4}{He}$ , ${}^{12}C$ , ${}^{20}{Ne}$ , and ${}^{56}{Fe}$ projectiles and the predictions of a linear transport model.
