摘要
本文在分析HELIOS协作组所提供的^(16)O-A碰撞的横能量分布实验数据的基础上,指出在靶裂区考虑非几何效应的必要性,并在几何模型的框架下,把非几何效应等效地用参与碰撞核子数的涨落来描述.
Based on the analyses of the transverse energy distributions data measured by the HELIOS collaboration group on ^(16)O-A collisions experiments at 200 A GeV, the necessity of considering non-geometrical effects in target fragmentation is pointed out, and these effects are described equivalently by the fluctuation of the number of participating nucleons in the framework of geometrical model.
