摘要
测量了46.7MeV/u^(12)C束流轰击不同靶核的核反应中前方向出射的类弹碎片,发现弹核碎裂产物的最可几能量可用Abrasion图象来解释。它们的平行动量分布宽度满足Goldhaber关系式,实验中提取的约化平行动量分布宽度σ_0=80±10MeV/c,接近于相对论情形下的值,并且σ_0对于不同的反应系统有相近的值。
The projectile-like fragments emitted from 46.7 MeV/u ^(12)C induced reactions have been measured. The most probable energies of the PLFs due to the projectile fragmentation can be reproduced within the Abrasion picture. Their parallel momentum distribution widths are found to fulfill the Goldhaber relation and the extracted reduced parallel momentum distribution width σ(?) is 80±10 MeV/c, which is close to the value obtained in the relativistic energy region. Futhermore, the values of σ_0 are the same for different reaction systems in our experiment.
