positron electron annihilation

基本解释

We investigate physicss properties of positronium and the way of positron - electron annihilation.
探讨正电子偶素的物理性质以及正电子—电子对的湮灭方式。
One signature of positron-electron annihilation is gamma rays carrying 511 thousand electron-volts (keV) of energy.
电子-正电子湮灭的一个信号就是携带511keV能量的伽玛射线。

One way to create such short bursts of gamma rays is through the collision -- and subsequent annihilation, as the mass of those particles converts into energy -- of an electron and a positron.
制造伽马射线短脉冲的一种方法，是电子与正电子的碰撞——之后的湮灭，使粒子的质量转化为能量。
