中文说明：正电子是反粒子的电子的和当它们相互作用，他们可以用2背面的发射来备份伽玛光子湮灭。和这些湮没伽玛光子进行湮灭的地方，这是正电子湮没实验的基本原理和可用于研究固体的性质的电子环境的能量和动量的信息[1，2]。正电子湮没谱（PAS）技术可以分为两类：第一是电子密度的研究，这是通过使用正电子湮没寿命谱（PALS）测量;另一个是用来获取缺陷的电子动量分布。这后一组包括多普勒展宽光谱（DBS），符合多普勒展宽光谱（CDBS）和湮没辐射（ACAR）的角关联的。用理查德森露西反卷积迭代算法来解谱
English Description：
Electrons and positrons are when they interact, they can be used to back up the back of launching two antiparticle annihilation gamma photons. And annihilation gamma photon annihilation of these places, which is the basic principle of positron annihilation experiments and can be used to study the electronic properties of solids in the energy and momentum of environmental information [1,2]. Positron annihilation spectroscopy (PAS) technology can be divided into two categories: The first is the study of electron density, which is the annihilation lifetime spectroscopy (PALS) by using positron measurements; the other is used to get the defective electron momentum distribution. This latter group includes Doppler broadening angular correlation spectroscopy (DBS), in line with the Doppler broadening spectrum (CDBS) and annihilation radiation (ACAR) a.
