The x-ray energies and transition rates associated with single and doubleelectron 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-Fockmethod. An appropriate electron correlation model is constructed with the aidof the active space method, which allows the electron correlation effects to bestudied efficiently. The contributions of electron correlation and the Breitinteraction to the transition properties are analyzed in detail. It is foundthat the two-electron one-photon (TEOP) transition is correlation sensitive.The Breit interaction and electron correlation both contribute significantly tothe 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 holedecay processes of He-like ions.
