氦原子3^3D—2^3P衰变Stokes参数的测定

The Measurement of the Stokes Parameters of Helium 3~3D-2~3p Decay

本文用电子-光子符合实验技术,通过偏振分析,在一定入射电子能量和背景气体压力下,同时得到氦原子3~3D-2~3P衰变的四个Stokes参数。

The measurements have been made of the stokes parameters of 3~3D-2~3P decay under specified incident electron energy, scattering angle and background pressure by using electron-photon coincidence technigue and polarization analysis.
