摘要:

利用Jülich模型的$\bar N N$振幅作为输入,在Glauber-Sitenko方法中考虑了束流能量低于300 MeV时反质子在$^3\He$和$^4\He$靶上的散射.得到了与现有的$\bar p ^4\He$微分截面、$\bar p ^3\He$和$\pbar ^4\He$反应截面数据的良好一致性。极化总$\bar p ^3$他截面的预测,计算内的单散射近似,包括库仑核干涉效应。极化建立的动力学进行了讨论。

英文摘要:

Antiproton scattering off $^3\He$ and $^4\He$ targets is considered at beam energies below 300 MeV within the Glauber-Sitenko approach, utilizing the $\bar N N$ amplitudes of the Jülich model as input. A good agreement with available data on differential $\bar p ^4\He$ cross sections and on $\bar p ^3\He$ and $\pbar ^4\He$ reaction cross sections is obtained. Predictions for polarized total $\bar p ^3$He cross sections are presented, calculated within the single-scattering approximation and including Coulomb-nuclear interference effects. The kinetics of the polarization buildup is discussed.
