| 摘 要： | 用小相对动量区域2π干涉学分析方法研究了相对论非对称重离子碰撞中π介子的吸收存在时对2π干涉学分析所得π源参数的影响,得到了不考虑和考虑π的吸收情况下所得到的源的参数的解析关系.与相对论非对称重离子碰撞1.8A GeVAr+Pb的实验结果进行了对比.

| Abstract: | The effect of the absorption of pion mesons in relativistic asymmetrical heavy ion collisions on pion source parameter is studied with two pion interferometry at small relative momentum. The relations between the source parameters are obtained when the pion absorption is considered or not. Comparison with the experimental measurements of relativistic asymmetrical central heavy ion collisions 1.8 A GeV Ar Pb is made. |
