Abstract

The global correlation in the observed variation with mass number of the $E 2$ and summed $M 1$ transition strengths is examined for rare-earth nuclei. It is shown that a theory of correlated $S$ and $D$ fermion pairs with a simple pairing plus quadrupole interaction leads naturally to this universality. Thus a unified and quantitative description emerges for low-lying quadrupole and dipole strengths.
