摘要: Diverse experimental information is analyzed to show that all the N = 82 isotones with Z 58, 60, 62, 64, 66, 68, and 70 are doubly ''magic'' nuclei. Also, nuclei in this region shown exhibit identical behavior, i.e., they similar many ways. The implications of discovery for interacting boson model other areas physics discussed.
