    "abstract": "The even--even and even--odd nuclei $^{126}$Xe-$^{132}$Xe and\n$^{131}$Ba-$^{137}$Ba are shown to have a well-realized $SO_8 \\supset SO_6\n\\supset SO_3$ fermion dynamical symmetry. Their low-lying energy levels can be\ndescribed by a unified analytical expression with two (three) adjustable\nparameters for even--odd (even--even) nuclei that is derived from the fermion\ndynamical symmetry model. Analytical expressions are given for wavefunctions\nand for $E2$ transition rates that agree well with data. The distinction\nbetween the FDSM and IBM $SO_6$ limits is discussed. The experimentally\nobserved suppression of the the energy levels with increasing $SO_5$ quantum\nnumber $\\tau$ can be explained as a perturbation of the pairing interaction on\nthe $SO_6$ symmetry, which leads to an $SO_5$ Pairing effect for $SO_6$ nuclei.",
