When electrons collide with the foil, positrons are formed in the flow.

当电子与金属箔相撞时，正电子在流动中形成。

Using a PET scan technology that he helped develop and partly owns.

One possible explanation is that these excess positrons are a by-product of dark matter interactions.

这些多余的正电子暗物质间相互作用的副产物。

It begins to decay and emit positrons, aka, anti electrons.

它开始衰变并释放正电子，也就反电子。

A positron for example is just like an electron but it has positive charge.

比如一个正电子，就一个电子，有一个单位正电荷。

The collision first forms a neutron, and then a positron.

Oppenheimer's early research was devoted in particular to energy processes of subatomic particles, including electrons, positrons, and cosmic rays.

奥本海默早期的研究特别致于亚原子粒子，包括电子、正电子和宇宙射线的能量过程。

The positron then immediately finds an electron, the two annihilate making a tiny flash of light, a photon.

正电子马上找到一个电子，这两个湮灭时产生光子的微小闪光。

These may be an electron and its antimatter equivalent, a positron, or two heavier leptons, a muon and an antimuon.

它们可能一个电子和它的反物质等价物，一个正电子，或者两个更重的轻子，一个介子和一个反介子。

Positrons are essentially electrons with positive charge.
