1.	Abdo, A. A., et al. (author) Fermi Large Area Telescope Search for Photon Lines from 30 to 200 GeV and Dark Matter Implications 2010 In: Physical Review Letters. - 0031-9007 .- 1079-7114. ; 104:9, s. 091302- Journal article (peer-reviewed)abstract Dark matter (DM) particle annihilation or decay can produce monochromatic gamma rays readily distinguishable from astrophysical sources. gamma- ray line limits from 30 to 200 GeV obtained from 11 months of Fermi Large Area Space Telescope data from 20-300 GeV are presented using a selection based on requirements for a gamma-ray line analysis, and integrated over most of the sky. We obtain gamma-ray line flux upper limits in the range 0.6-4.5 x 10(-9) cm(-2) s(-1), and give corresponding DM annihilation cross-section and decay lifetime limits. Theoretical implications are briefly discussed.
