摘要:

本文介绍了在GSI的高分辨磁谱仪-碎片分离器(FRS)上测量的1AGeV的136 Xe和124 Xe反应在铅靶中产生的核素截面和残留物的纵向速度分布。这些数据涵盖了136的Z = 3和Z = 56之间以及124的Z = 5和Z = 55之间的广泛同位素范围,甚至达到了一些微仓的截面。速度分布表现出高斯形状的质量A = 20以上,而更复杂的行为,观察到较轻的质量。两种反应的同位素分布在整个残留物质量范围内保持对抛射体N/Z比的记忆。

英文摘要:

This paper presents the nuclide cross sections and the longitudinal velocity distributions of residues produced in the reactions of 136Xe and 124Xe at 1 A GeV in a lead target, measured at the high-resolution magnetic spectrometer, the Fragment Separator (FRS) of GSI. The data cover a broad range of isotopes of the elements between Z = 3 and Z = 56 for 136Xe and between Z = 5 and Z = 55 for 124Xe, reaching down to cross sections of a few microbarns. The velocity distributions exhibit a Gaussian shape for masses above A = 20, while more complex behaviour is observed for lighter masses. The isotopic distributions for both reactions preserve a memory on the projectile N/Z ratio over the whole residue mass range.
