氮原子同位素计算

Theoretical Calculation on Isotope Shifts of N(I)

本文利用多组态Dirac-Hartree-Fock和相对论组态相互作用的方法计算了氮原子的同位素14N和15N的四对能级跃迁:3s^4P→3p^4P°,3s^4P→3p^4D°,3s^2D→5p^2D°,和3s^2P→3p^2P^°相应的特殊质量位移系数和场因子.由计算所得的正常质量位移,特殊质量位移系数和场因子获得了氮原子同位素的正常质量位移、特殊质量位移和场位移.同时将计算结果和报道的实验和理论计算结果进行了比较.

The special mass shift coefficient and field parameter factor of four multiples,3s^4P→3p4P°,3s^4P→3p^4D°,3s^2D→5p^2D°,and 3s^2P→3p^2P°,of ^14N and ^15N were studied using the multi-configuration Dirac-Hartree-Fock method and the relativistic configuration interaction approach.The normal mass shifts,special mass shifts,field shifts,and isotope shifts of N(I)were derived from the theoretical calculated normal mass shift parameter,special mass shift parameter and field parameter factor,and compared with the reported experimental measurements and theoretical results.
