| 摘要: |
| 基于文献[1,2]方法,提出了粒子群关联概念,并以此建立了一种检测集合流的新方法。采用新方法对1,2AGeVAr+BaI2碰撞的Bevalac流光室4π实验事件粒子群的关联进行了研究。通过与蒙特卡罗结果比较,推测该实验事件集合流的"集体性"不小于80%。 |

| Abstract: |
| On the basis of references, a concept of particle-group correlations and a new method of collective flow measurement are proposed.Using this new method,the particle-group correlations arising from collective flow are studied with 4π data for 1.2 A GeV Ar+BaI2 collisions at the Bevalac streamer chamber.Comparing with Monte Carlo results,the collectivity of particles in the final state of this collision has been inferred to be more than 80%. |
