  The double electron E1 transition energies, probabilities, and oscillator
strengths between the $2s2p^{n}$ and $1s^{2}2p^{n-1}$($1\!\leq\!n\leq\!6$)
configurations of Xe$^{q+}$($47\!\leq\!q\leq\!52$) ions with different
spectator electrons have been calculated based on the multi-configuration
Dirac-Hartree-Fock method. A reasonable electron correlation model is
constructed with the aid of the active space method. The finite mass of
nuclear, Breit interaction and QED effects have also been included. The
calculated results are in good agreement with the available data. The
theoretical spectra of different spectator electrons of the double K hole state
have been predicted. The spectator electron effects on the transition spectra
have been analyzed in detail. The present results will be helpful for analyzing
the high energy X-ray spectrum observed from the interaction between high
energy highly charged ions and the surface.
