Abstract
The effect of SL-dependent configuration interaction (SL-CI) on the hyperfine structure of a complex atom is first determined accurately. The radial integrals for the iron atom evaluated from the experimental data corrected to second-order perturbation theory are the following (in a.u.) : for the 3d7 4s configuration < r-3 >01 = 3.913, < r-3 >12 = 3.982, < r-3 > 10 = - 2.087 and [dP4s(r)/dr]2 0 = 37.0 , and for the 3d6 4s2 configuration < r-3 >01 = 4.518, < r-3 >12 = 4.594 , < r-3 >10 = - 0.722 . The values of the parameters describing SL-CI in dNs configurations, according to Bauche-Arnoult notation, are : x2=x3=0.08, x4=-0.062, x7 = 0.068 , x11 = -0.113Keywords
