Abstract [en]

Hyperfine-induced transitions (HIT) have recently attracted a lot of attention especially for its applications in astrophysics [1, 2]. Owing to their nature, HIT can be used to determine the relative isotope abundances and for low-density plasma diagnostics. For C-like ions, the fine structure interval between the 2s2p3 3Po0 and 2s2p3 3Po1 levels is quite small [3, 4], which results in strong state mixing in the presence of the hyperfine interactions. Consequently, large HIT probabilities are expected for many elements through the isoelectronic sequence. Using the GRASP2K package [5] and the MCDF-GME program [6] we calculate the HIT rates for a few abundant elements in stars. Stress is put on the interference effects between individual transition amplitudes that contribute to the HIT. In addition, some possible experiments will be suggested for a promising isotope analysis in stars.
