- Аннотация: The reemission of energy by a platinum atom as a result of photoionization and subsequent cascade decay of vacancies is studied at incident photon energies of 0.01–1000 keV. The energy acquired by the Pt atom upon photoionization is split into the following channels: a) energy stored in final cascade ions, b) energy reemitted by cascade electrons, and c) energy reemitted by cascade photons. These quantities, as well as the average energy of photoelectrons, are calculated depending on the energy of the incident photons. Channel (a) is significant only in the UV and soft X-ray regions up to 2 keV. In the incident photon energy range from O2 to K ionization threshold, channel (b) dominates. Channel (c) prevails at photon energies above the K-threshold. When platinumcontaining agents are used as radiosensitizers in radiation therapy of cancer, cascade electrons and photoelectrons are shown to be principal depositors of energy to the tumor.
