antineutron

n.反中性子

The nuclide chart involves electron, positron, antiproton, antineutron, photon to exhibit the symmetry of mass and charge ideally. 该核素图将电子、正电子、反质子、反中子和光子收录在内，完美地表现了质量和电荷的对称性。

antineutron reaction 反中子反应

3.Scientists in 1995 succeeded in producing anti-atoms of hydrogen, and also anti-deuteron nuclei, made out of an antiproton and an antineutron, but not yet more complex antimatter. 科学家在1995年成功生产了氢的反原子,以及反氘核核子,由一个反质子和一个反中子生成,仅仅还不能是更为复杂的反物质。
