高电荷态N~(4＋)与Na原子碰撞过程中靶原子激发截面的测量

Abstract

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 N 4+ ion and Na atoms. The experimental results show that the excitation cross sections of NaI(3p-3s) are very large, about 10 -15 cm 2 . 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.国家自然科学基金，中国原子分子物理数据研究联合
