【 摘 要 】

Absolute rate coefficients for dielectronic recombination (DR) of Li-like136Xe51+have been measured at the heavy-ion storage ring ESR. The experimental results are compared with relativistic distorted-wave calculations employing the multiconfiguration Dirac-Fock method. Based on the DR measurements the 2s-2p1/2and 2s-2p3/2excitation energies in Li-like Xe51+were determined with a relative accuracy of ∼400 ppm.
