Abstract:	We have studied the variation of the excitation energy, electric multipole decay rate and g factor of the lowest lying 2+ and 3- states of even-ZN = 50 isotones as a function of the mass number in relativistic quasiparticle random phase approximation. Overall agreement with the available data is quite satisfactory considering the wide range of the number of nuclei and their excitation properties in a microscopic approach having no free adjustable parameter. Also predictions are made for several nuclei. We find that increase in the pairing interaction strength, in general, improves the agreement with the data for 3- states but it affects adversely the results for the 2+ states.
