Evaluation of the electron capture by the H-like Gd ion within line-profile approach

The electron capture by the H-like Gd ion is evaluated within the frames of the line-profile approach (LPA). The energy and widths of the double-excited energy levels and the corresponding resonance strengths are calculated. With the employment of the results of our previous work, the resonance strengths for the H-like U ion were also calculated and compared with the recent experimental and theoretical data. This calculation partly takes into account the interelectron interaction to all orders of QED perturbation theory. The lowest-order radiative corrections are also included. The LPA produces results for both dielectronic and radiative recombination.
