    "abstract": "The global correlation in the observed variation with mass number of the $E2$\nand summed $M1$ transition strengths is examined for rare earth nuclei. It is\nshown that a theory of correlated $S$ and $D$ fermion pairs with a simple\npairing plus quadrupole interaction leads naturally to this universality. Thus\na unified and quantitative description emerges for low-lying quadrupole and\ndipole strengths.",
