Emission at 13.2 nm from the 4d S0 -4p P1 laser transition of Ni-like Cd was observed in a cadmium vapor plasma column excited by a high-current capillary discharge. The dynamics of the plasma were studied using time-resolved soft x-ray pinhole images and hydrodynamic simulations. The pinhole images show that the plasma column maintains a good symmetry up to the time of maximum compression. Fifty-five CdXXI lines were identified in the 12.7 -18.4 nm region with the assistance of calculations performed using the Slater-Condon method with generalized least-squares fits of the energy parameters.
