Description
Mixed-symmetry states have proven their sensitivity to the shape evolution across quantum phase transitions. Especially the electromagnetic transitions between the $1^+$ scissors mode and the $0^+_2$ state are strongly affected by the amount of nuclear deformation. Also the elusive $E2$ properties of mixed-symmetry states can be established as novel signatures for phase-transitional behavior. First experimental information on such is discussed for the transitional nucleus $^{154}$Gd and the quadrupole deformed nuclei $^{156}$Gd and $^{162,164}$Dy in connection with calculations in the IBM2.
