10.7 AGeV ^(197)Au诱发乳胶核反应α射弹碎片分布

Distribution of Helium Projectile Fragments From ^(197)Au-Emulsion Interactions at 10.7 AGeV

对10.7 AGeV 197Au诱发乳胶核反应α射弹碎片产生的分截面进行研究。讨论了197Au核碎裂产生α多重碎片的产生率,并与其它能区的相应实验结果进行了比较。实验结果表明,α射弹碎片多重数分布服从KNO标度无关性。

The measurement of partial production cross-sections of the multiple helium projectile fragments emitted at 10.7 AGeV 197^Au-emulsion interaction is reported. The production rate of helium fragment due to fragmentation of 197^ Au ion is studied and compared with that obtained from same projectile at different energies. It is found that the multiplicity distribution of helium projectile fragments obeys a KNO scaling.
