摘要
由不同有效质量m~*/m与压缩系数K所标示的平均场的非相对论Buu计算,研究了横动量的产生机制,并讨论了m~*/m和K对横动量等的影响。发现横动量对K的依赖不太灵敏,但对m~*/m却十分灵敏。
The transverse momentum distributions in heavy ion collisions have been investigated in the non-relativistlc BUU approach for different mean field interactions characterized by the effective mass m~* and the compression modulus K. The production mechanism of the transverse momentum has been analysed. It is found that the transverse momentum is very sensitive to the effective mass and less sensitive to the compression modulus.
