AbstractThe role of T-50 in classifying gamma-ray bursts (GRBs) is investigated. We take T-50 = 0.7 s as the line of division and find that some bursts belonging to the class of long bursts defined by T-90 > 2 s now become short bursts (sample 1) while some belonging to the class of short bursts defined by T-90 < 2 s now become long bursts (sample 2). We study how these sources are affected by the two methods of classification and find the change of classes of sample 1 is due to some peculiar properties of the light curves. Based on their characters, most of the bursts of sample 1 should be taken as short bursts.
