N2  - Magnetars are newly discovered cosmic sources of high engergy radiations that emit short intense bursts of x - rays and {u03D3}-rays. Studying the spectral and temporal properties of these bursts of SGR 1900+14 allows us to identify the physical mechanism responsible for their emission and to probe the interaction of radiation and matter at extreme conditions of temperature gravity and magnetic field that cannot be reproduced in earth - based laboratories or paticle accelerators
