Cold positron interactions with ultracold rubidium atoms

反粒子和反物质已经从理论和科幻小说发展成为纯科学和应用科学的一个重要和令人兴奋的领域。这个基础原子物理项目旨在进一步研究反物质和物质如何相互作用，通过创新地结合两种尖端原子物理技术，首次提供正电子（电子反粒子）与被困铷原子相互作用的综合实验结果。它旨在提供许多基本相互作用量的测量以及物质和反物质之间的碰撞。这将测试最新的量子理论方法，并进一步加深我们对反物质在医学和材料科学中的应用的理解。

Antiparticles and antimatter have progressed from theory and science fiction to become an important and exciting area of pure and applied science. This fundamental atomic physics project aims to further study how antimatter and matter interact by providing the first comprehensive experimental results for the interaction of positrons (the electron anti-particle) with trapped rubidium atoms in an innovative combination of two cutting-edge atomic physics techniques. It aims to provide measurements of many fundamental interaction quantities and for collisions between matter and antimatter. This will look to test the latest quantum theoretical approaches and further our understanding of the uses of antimatter in medical and materials science.
