Positron and electron (particle and anti-particle) can annihilate in collision turning into electromagnetic radiation.
正电子和电子(粒子和反粒子)在对撞中会发生湮灭，并产生电磁辐射。
2
Optical absorption spectra and positron annihilation radiation Doppler broadening were measured at room temperature.
在室温条件下测量了吸收光谱与正电子湮没辐射多普勒展宽谱。
3
They have analyzed data collected from the neutrino beam at LNGS and have found no evidence of radiation or electron-positron pairs coming from the neutrinos.
