We present an outlook of studies performed in collaboration or inspired by Prof. Mahir Hussein. The first part refers to the elastic scattering measurements performed in the 80–90 with α-structured systems with strong oscillations in the angular distributions and a large increase of the cross-sections at backward angles, an effect called Anomalous Large Angle Scattering (ALAS). The second part refers to the installation of the “Radioactive Ion Beams in BraSil” (RIBRAS) facility, which was an idea promoted by Prof. Hussein and became reality due to his strong support. It was installed in 2004 as the first radioactive ion beam facility in the southern hemisphere and it has been operating continuously since then. In this paper, we will describe the facility, and some interesting results obtained with the 2-neutron-halo, exotic ⁶He beam, provided by RIBRAS.

我们展示了由Mahir Hussein教授合作完成或受到启发的研究前景。第一部分涉及在80–90中使用α进行的弹性散射测量结构的系统，在角分布中具有强烈的振荡，并且在向后的角度处具有较大的横截面增大，这种现象称为反常大角度散射（ALAS）。第二部分涉及“巴西的放射性离子束”（RIBRAS）设施的安装，这是侯赛因教授提倡的想法，由于他的大力支持而成为现实。它于2004年安装，是南半球的第一个放射性离子束设施，此后一直在连续运行。在本文中，我们将描述该设施，以及由RIBRAS提供的2中子晕，奇异的⁶ He光束获得的一些有趣结果。
