我们描述了N5+(1S2)从He和H2中俘获单电子后N4+(1s23P2P3/2)的偏振光谱测量。测量了3s2s1/2-3p2P3/2转变的偏振度P随入射速度的变化，范围在0.38-0.54A.U之间。在这两个碰撞系统中，P在这个速度范围内几乎是恒定值，即He为0.2，H2为近零。讨论了在偏振度中观察到的强烈的目标依赖性。
We describe polarization spectroscopy measurements of N4+(1s23p 2P3/2) following single electron capture by N5+(1s2) from He and H2. The degree of polarization P for the 3s2S1/2–3p 2P3/2 transition has been measured as a function of projectile velocity ranging between 0.38 and 0.54 a.u. In both of the collision systems, P has a nearly constant value in this velocity range, namely 0.2 for He and approximately zero for H2. The strong target dependence observed in the degree of polarization is discussed.
