3.7 A GeV ^(16)O诱发乳胶核反应簇射粒子的间歇性

The Intermittency of Shower Particles in 3.7 A GeV ^(16)O Induced Nuclear Emulsion Reaction

本文利用标度阶乘矩方法,研究了3.7 A GeV16O诱发乳胶核(Em)反应簇射粒子分布的涨落,发现其具有间歇性行为,即动力学涨落.不同能量下16O与乳胶核中AgBr反应产生的簇射粒子在赝快度空间的间歇性相比较,发现间歇性的强弱与能量没有关系.3.7 A GeV16O诱发乳胶核反应簇射粒子在方位角空间分布的间歇性随耙核(CNO、Em、AgBr)的增大而增强.

The fluctuation of shower particles in 3.7 A GeV 16O induced nuclear emulsion reaction is studied by using the scaled factorial moments methods.The intermittent behavior,that is dynamics fluctuation,is found.The intermittency of shower particles in pseudorapidity space is compared with the results at 60,200 A GeV.It is found that the intermittency is independent of projectile energy.The fluctuation of shower particles in azimuthal space is dependent of the mass of target,and it is found intermittent index i...
