We employ the suite of atomic physics codes to model the inner-shell X-ray emission spectrum of xenon clusters and compare results with those obtained via observation by high-resolution X-ray spectroscopy the emission of Xe clusters irradiated by 30 fs laser pulses. We find that the commonly employed configuration average approximation breaks down and significant spin-orbit splitting necessitates a detailed level accounting. Additionally, were produce an interesting spectral trend for a series of experimental spectra taken with varyingpulse laser energy for fixed pulse duration.
