摘要：

Numerical procedure is developed for analyzing impurity-induced resonant-state STM images observed in high-T-c superconductors, and is applied to three sets of higher resolution data provided to us by J. C. Seamus Davis and E. W. Hudson. Each image is associated with a Zn impurity in Bi2Sr2CaCu2O8. The averaged, integrated, relative quasiparticle local density of states at all predominant Cu(Zn)-sites near a Zn impurity is extracted. The results can be used to test the predictions of all existing and future tight-binding-type theories on such images.
