Özet

Background: A characteristic observable of nuclear collective motion is the relative B(E2) values from the gamma band to the ground band in even-even deformed nuclei. TheAlaga rules provide an idealized set of benchmarks for these observables. However, deviations from the Alaga rules are universally observed and have been traditionally and successfully interpreted in terms of parameterized gamma-band-ground-band bandmixing. An alternate approach, partial dynamical symmetries, has no bandmixing whatsoever and is parameter free, yet mimics closely the effects of bandmixing, due solely to the effects of finite valence nucleon number.
