This article considers the possibility of applying the positron annihilation spectroscopy method for investigating the pore space of rocks from oil-gas and methane-coal deposits. The diagnostics of the structure was performed using the method of spectrometry of angular correlation of annihilation rays (ACAR). Using the samples of porous silicon, the authors have shown the applicability of the ACAR...

Positron annihilation spectroscopy techniques are sensitive laboratory methods of in-depth study of the material structure and processes occurring in it. The digital spectrometric system described in this paper is designed to study the defect structure of materials by positron annihilation spectroscopy techniques. This system combines the methods of positron annihilation lifetime spectroscopy and...
The Government of the Russian Federation has intention to develop nuclear energy and involve in the fuel cycle additional amount of fissile materials. In theory it could lead to increasing activities of terrorist's groups by using nuclear materials as an object for blackmailing. The governmental system of nuclear material control and accounting was dedicated to prevent alike scenarios. Unfortunately,...
