  The x-ray energies and transition rates associated with single and double
electron radiative transitions from the double K hole state $2s2p$ to the
$1s2s$ and $1s^{2}$ configurations of 11 He-like ions ($10\!\leq\!Z\!\leq\!47$)
are evaluated using the fully relativistic multi-configuration Dirac-Fock
method. An appropriate electron correlation model is constructed with the aid
of the active space method, which allows the electron correlation effects to be
studied efficiently. The contributions of electron correlation and the Breit
interaction to the transition properties are analyzed in detail. It is found
that the two-electron one-photon (TEOP) transition is correlation sensitive.
The Breit interaction and electron correlation both contribute significantly to
the radiative transition properties of the double K hole state of He-like ions.
Good agreement between the present calculation and previous work is achieved.
The calculated data will be helpful to future investigations on double K hole
decay processes of He-like ions.
