    14. ABSTRACT This report results from a contract tasking P. N. Lebedev Physical Institute as follows: The singlet oxygen O2(1Delta), O2(1Sigma) can be used for medical treatment, sterilization, the deactivation of biological and chemical agents, as source of the energy for gas lasers. The most efficient singlet oxygen generators (SOG) are based on the reaction of chlorine with the basic hydrogen peroxide (BHP). In the frame of the proposed project the bubble SOG with BHP layer under centrifugal acceleration will be developed and studied. This type SOG has not been studied in up to now. The efficiency of the chlorine absorption and O2(Delta) generation in the BHP under centrifugal acceleration is one of the task of the proposed project. Three versions of the SOGs with the BHP layer under centrifugal acceleration will be developed and studied. Finally it is proposed to develop an efficient source of singlet oxygen for applications in science and technology. The results of this project will be discussed with representatives of Partner and will be published in common report on conferences and articles. The personnel of the participant have 20 years experience in study and development of different types SOG. The laboratory of the participant is equipped with devices, facilities and methods for investigations of SOG. The personnel of participant successfully executed projects in development of SOG including in the frame of ISTC projects 1826P, 2230P. Meeting the goals of this project helps Russian scientists to integrate into international scientific cooperation, supports basic and applied research and design for peaceful purposes.
