    "abstract": "Spectra from xenon ions have been recorded at the NIST EBIT and the emission\ninto a 2% bandwidth at 13.5 nm arising from 4d-5p transitions compared with\nthat from 4d-4f and 4p-4d transitions in Xe XI and also with that obtained from\nthe unresolved transition array (UTA) observed to peak just below 11 nm. It was\nfound that an improvement of a factor of five could be gained in photon yield\nusing the UTA rather than the 4d-5p emission. The results are compared with\natomic structure calculations and imply that a significant gain in efficiency\nshould be obtained using tin, in which the emission at 13.5 nm comes from a\nsimilar UTA, rather than xenon as an EUVL source material.",
