We have measured the X-ray emission spectra of a plasma generated by laser radiation with an intensity above 10$$^{19}$$ W/cm$$^2$$ and a pulse duration of 30 fs acting uon an argon jet target with a large aboundance of micron-sized clusters. The time variation of the X-ray yeild from various multiplicities, calculated within the framework of a nonstationary kinetic model, shows a good qualitative agreement with the experimental time-integrated spectrum.
