Being able to look at entire anti-atoms might give some further clue.
通过观察完整的反原子,科学家或许能得到进一步的线索。
Last November the ALPHA collaboration at CERN, which Dr Hangst leads, managed to putpositrons into orbit around 38 antiprotons-thus creating anti-hydrogen atoms-and then heldon to them in a magnetic trap for a few tenths of a second.
去年11月,欧洲原子核研究组织阿尔法合作项目负责人Hangst博士设法将一些正电子分别放入38颗反质子的轨道这样就产生了反氢原子然后让它们在电磁阱中存留零点几秒的时间。
Now, as they report in Nature Physics, the researchers have used their device to preserveanti-hydrogen for 16 minutes .
现在,研究人员在自然物理杂志上发表的报告称,他们已经利用设计的装置将反氢子存在时间延续到了16分钟。。
This gives the anti-atoms plenty of time to settle into their ground state, the most stablecondition a particle or atom can attain.
这给反原子充分的时间进入能量基态,这是粒子或原子所能获得的最稳定状态。
As a result, Dr Hangst and his colleagues can look in a leisurely manner for novel ways thatantimatter might differ from the common-or-garden variety.
因此,Hangst博士及其同事能够寻找新的途径从容地观测反物质可能与普通物质存在的差别。
