Abstract: 
SmFeAdsO1-xFx was irradiated in a fission reactor by a fast (E>0,1 MeV) neutron fluence of 4 x 1021 m-2. The introduced defects increased the normal state resisitivity due to a reduction in the mean free path of the charge carries. This leads to an enhancement of the upper critical field at low temperatures. The critical current density within the grains, Jc, increases upon irradiationl. The second maximum in the field dependence of Jc dissapears and the critical current density becomes a monotonically decreasing function of the applied magnetic fields.
