Zusammenfassung:his work, the half-life of the (155)Sm beta (-) decay was determined using enriched (154)Sm samples submitted to irradiation in the DEA-R1 reactor of IPEN; the activity of the samples were followed for 4-5 consecutive half lives using a 198cm3 HPGe detector. The data was corrected using a non paralizable dead time correction and fitted to an exponential decay function using a non linear fitting procedure developed on the MatLab platform. The resulting value-T(1/2) = 22.180(26) min-was compatible to the one found in the literature, with a lower uncertainty.
