摘　　要：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.
