| Summary: | Заглавие с экрана Currently, positron annihilation methods are the most effective methods of studying the defect structure of the substance. The radioisotopes are usually used as sources of positrons inmethods of positron annihilation. In this research, the contribution of Ti44 source in positron lifetime spectra is studied. The experiment was performed by positron lifetime spectrometry. As a result of this experiment the dependence of Ti44 source contribution on atomic number of studied element was obtained.This dependence was described by the function, obtained by the least squares method. This function can be used for Ti44 source contribution evaluation for any material. |
