positron electron annihilation

基本解释

We investigate physicss properties of positronium and the way of positron - electron annihilation.
探討正電子偶素的物理性質以及正電子—電子對的湮滅方式。
One signature of positron-electron annihilation is gamma rays carrying 511 thousand electron-volts (keV) of energy.
電子-正電子湮滅的一個信號就是攜帶511keV能量的伽瑪射線。

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.
制造伽馬射線短脈沖的一種方法，是電子與正電子的碰撞——之後的湮滅，使粒子的質量轉化爲能量。
