测量了高电荷态N4+与Na原子碰撞中靶原子的发射截面和激发截面,发现NaI(3p→3s)谱线的激发截面很大,约为10-15cm2.实验给出了发射截面和激发截面数据,并进行了定性的讨论The emission cross sections and excitation cross sections have been measured in collisions between N4+ ion and Na atoms. The experimental results show that the excitation cross sections of NaI(3p-3s) are vety large, about 10-15cm2 . The data of cross sections have been given in this paper and reasons for the large excitation cross sections of NaI(3p-3s) have been discussed qualitatively.
