| 英文摘要 | We present a theoretical investigation of the hyperfine structure of the 5s5d (3)D(2)-5s4f (3)F(2,3)(0) transitions in In II. Earlier work has failed in determining hyperfine constants for the upper levels of these transitions. We show that this is due to strong off-diagonal hyperfine interaction, which not only changes the position of the individual hyperfine lines but also introduces large intensity redistributions among the different hyperfine levels. We present hyperfine dependent gf-values and show that off-diagonal hyperfine interaction reduces some of the gf-values by two orders of magnitude, while others are increased by up to more than a factor of 6. We also discuss the influence on the hyperfine structure of an accurate representation of the level-splitting of the 5s4f configuration. We show that the hyperfine interaction in (3)F(3)(0) and (1)F(3)(0) is very hard to determine accurately even in a large-scale calculation, and we derive a semi-empirical method for adjusting our results using an experimentally known, diagonal hyperfine constant for 5s4f (1)F(3)(0). The resulting theoretical synthetic spectra reproduce the experimental values to high accuracy and facilitate the identification of all observed lines. |
