摘要：
The distribution of quadrupole phonon strength to low-lying states in nuclei is examined. It is found that the 21+ and 41+ states of all nuclei from Z=30to100 display almost perfect quadrupole phonon character even though they encompass widely ranging structures. The interacting boson approximation reproduces both the very small deviations from phonon purity and the distribution of those deviations as a function of mean field structure in a natural fashion. Simple physical mechanisms explain these results. © 1994 The American Physical Society.
