Dielectronic recombination (DR) is an important recombination process in the high temperature and astrophysical plasmas. In this talk we will show that it is possible to identify the energetically unresolved high ι states that contribute to DR by measuring the autoionization rate as a function of electric field. We measure the autoionization yields of the excited isotropic and anisotropic cores of Ba, 6p j nl, j=1/2, 3/2, ι >10 in the electric field and determine the highest ι such that the autoionization rate is equal to the radiative rate of Ba + 6p, AR=3.88Ã10 -9 .
