Popis:	Analysis of magnetic relaxation measurements on a 100% and 50% ex-situ Ti-sheathed MgB2 wire in terms of activation energy distribution are presented. It is shown, that in spite of strong restrictions of the method, credible results can be obtained, which give more information concerning the pinning behavior, than only investigation of critical current density can perform.
