摘要:

低能$p\bar{p}$相互作用被认为是考虑到两个粒子的极化。相应的截面用奈梅亨核子-反核子光学势计算。然后将它们应用于分析氢靶中极化质子与储存反质子相互作用产生的极化积累。它示出,在现实的参数的存储环和目标,过滤机制可以提供一个显着的偏振在一个时间与束寿命相媲美。

英文摘要:

Low energy $p\bar{p}$ interaction is considered taking into account the polarization of both particles. The corresponding cross sections are calculated using the Nijmegen nucleon-antinucleon optical potential. Then they are applied to the analysis of the polarization buildup which is due to the interaction of stored antiprotons with polarized protons of a hydrogen target. It is shown that, at realistic parameters of a storage ring and a target, the filtering mechanism may provide a noticeable polarization in a time comparable with the beam lifetime.
