根据微扰QCD理论，在渐近大动量转移下，核准排他反应应该是数学{propto}{A}^{1}$。在这里，我们分析了在有限能量下，当夸克系统变成强子并离开原子核时，夸克系统的膨胀如何修正渐近预测。我们发现，在目前可行的实验中，核透明现象应该是明显的，但透明程度对膨胀模型是敏感的。
According to perturbative QCD, nuclear quasiexclusive reactions should be $ensuremath{propto}{A}^{1}$ at asymptotically large momentum transfer. Here we analyze how the asymptotic prediction is modified at finite energies by the expansion of the quark systems as they become hadrons and exit from the nucleus. We find that the phenomenon of nuclear transparency should be apparent in presently fesible experiments, but the degree of transparency is sensitive to the expansion model.
