摘要： Dielectronic recombination cross sections and rate coefficients of He-like Kr are calculated employing the relativistic Flexible Atomic Code (FAC) in which autoionization rates are calculated based on relativistic distorted-wave approximation and the configuration interaction is considered. The Auger and total radiative rates of some strong resonances are listed and compared with the results from MCDF and HULLAC methods. The n-3 scaling law is checked and used to extrapolate rate coefficients. We also show the variation of DR branching ratio with different DR resonances or atomic number Z. The effect of radiative cascades on DR cross sections are studied.

关键词: dielectronic recombination, rate coefficients, radiative cascade, n-3 scaling law
