摘要:

推广了Giessen Boltzmann-Uehling-Uhlenbeck输运模型,并将其应用于宽动量范围内的反质子-核相互作用。将模型计算结果与原子核上$\bar p$ -吸收截面的实验数据进行了比较,着重讨论了反质子光学势实部的提取。还考虑了反质子在飞行中冷压缩原子核的可能性。

英文摘要:

The Giessen Boltzmann-Uehling-Uhlenbeck transport model is extended and applied to the antiproton-nucleus interactions in a wide beam momentum range. The model calculations are compared with the experimental data on $\bar p$-absorption cross sections on nuclei with an emphasis on extraction of the real part of an antiproton optical potential. The possibility of the cold compression of a nucleus by an antiproton in-flight is also considered.
