We present a new approach to investigate the evolution of collectivity on the nuclear map based on the ratio R = B(E2; 2(1)(+) -> 0(1)(+))(exp)/B(E2;2(1)(+) -> 0(1)(-))(Q), where the quantity in the denominator is calculated using the quadrupole moment of the 2(1)(+) level when known. The systematics of such ratios in even-even nuclei reveals interesting features including signatures for particular collective excitations and sensitivity to shell- and subshell closures. A reproduction of these data by theoretical models is highly desirable with the potential to shed more light on the interplay between collective and single-particle motions. In particular, a new signature for shape coexistence was found: R < 1.
