Status of the GAMMA - 400 Project
A. M. Galper Trieste, Italy, May 2013 The main scientific objective of the GAMMA-400 Project, that was defined by Nobel laureate V. L. Ginzburg, is to search for peculiarity (of gamma-ray line) in the energy spectrum of high energy gamma radiation from discrete sources and diffuse radiation, that is the most effective method of solving the issue of the nature of dark matter.
