欧洲科学家最近研制出第一粒人造反原子——反氢原子。这个原子带有相反的电荷,一个带正电的电子围绕着一个带负电的质子运转。通常氢原子所带电荷与此相反。科学家首先在粒子加速器中制造出带负电荷的反质子,然后将反质子束射入氙气中,制造出反电子。至少在某种情况下,使一个反电子开始围绕着一个反质子运转,反氢原子就是这样造成的。 European scientists recently developed the first artificial anti-atom - anti-hydrogen atoms. This atom carries the opposite charge. A positively charged electron runs around a negatively charged proton. In general, hydrogen atoms carry the opposite charge. Scientists first in the particle accelerator to create negatively charged anti protons, and then the anti proton beam into xenon to create the anti-electron. In at least some cases, an anti-electron begins to operate around an anti-proton, which is what anti-hydrogen atoms do.
