Pseudorapidity distributions of charged particles emitted in $Au+Au$, $Cu+Cu$, $d+Au$, and $p+p$ collisions over a wide energy range have been measured using the PHOBOS detector at RHIC. The centralit...
测量了200A GeV 32S核与Cu作用产生的重碎片P,Si,Al和Mg的角分布,得出它们的横动量分布宽度σpt在130—270MeV/c的范围.
用阈探测器中子活化法测量了50MeV/u 18O离子轰击Be.Cu和Au厚靶的总中子产额和前向中子发射率. 实验结果表明,中子产额对靶核原子序数有一定的依赖性,较轻靶子的中子产额和中子发射率高于较重的靶子;当靶核(Cu)和入射离子单核能(50MeV)相同时,18O离子的中子产额约为12C离子的4倍.
用中子活化分析法对制造器件用的半导体硅中Na,Cu,Au含量的分析
