We have measured absolute L x-ray emission yields from (Xe)n clusters (with n in the range 10^5 – 10^7 atoms/cluster) irradiated by 60 femtoseconds 800 nm IR and 160 femtoseconds 400 nm UV laser pulses of 10^15 – 10^17 W cm-2 peak intensity. Measurements have been performed as a function of cluster size (backing pressure) and laser peak intensity. Identification of spectroscopic features as well as x-ray emission yield variation with laser wavelength and intensity are in strong contradiction with results and interpretation from previous studies.
