The aim of the scientific research work is hydrogen sorption by carbon nanotubes and electron-positron spectroscopy application. The automatic system Gas Reaction Controller (GRC) was used for measuring the hydrogen sorption capacity of carbon nanotubes. Positron annihilation spectroscopy (PAS) is unique method for characterization of defects, pores of carbon nanostructure materials and determination the hydrogen effect on nanotubes. Positron methods are based on experimental measurements of the parameters of annihilation positron implanted in the test material. These methods are divided into temporary, angular distribution of annihilation photons and Doppler broadening of annihilation line.
