高能强子-核和核-核相互作用中中间重子系统的形成和慢粒子的角分布
An intermediate baryon system formation and the angular distributions of the slow particles emitted in hadron-nuclear and nuclear-nuclear interactions at high energies
摘要：
我们分析了0.95AGeV的Kr+Em -反应和10.7AGeV的Au+Em -反应中发射的b-粒子的角分布，并与较轻的射弹实验进行了比较，后者观察到了慢粒子角分布中的某些结构。随着抛射体质量的增加，b粒子的相同结构几乎消失。我们认为这与核间次级相互作用速率的增加有关，而次级相互作用的增加可能主要导致中间重子系统形成信息的消失。我们建议在重离子相互作用事件产生时考虑它，以恢复中间重子系统形成的信息。
英文摘要：
We have analyzed the angular distributions of the b- particles emitted in Kr+Em -reaction at 0.95 A GeV and in Au+Em -reaction at 10.7 A GeV and compared these with lighter projectile experiments for which some structure in the angular distribution of slow particles was observed. The same structure for the b-particles almost disappears by increasing the projectile mass. We believe that it is connected with increasing rates of internuclear secondary interactions which could lead mainly to disappearance of the information about intermediate baryon system formation. We suggest that it should be taken into account at event generation for heavy ion interactions to restore the information on the intermediate baryon system formation.
