A number of VUV lines, produced in a theta-pinch plasma, have been identified in the triplet system of Cd-like Xe VII. They serve to establish the positions of all the 5s5p3P0, 5p23P, 5s6s3S, and 5s5d3D levels. An ionization energy of 743 000 ± 6000 cm 1 (92.1 ± 0.8 eV) is derived from these observations.
