Abstract

Experimental indications for the nuclear phase transitions described by the new symmetries E(5) and X(5) are discussed for the stable Ba, Nd, and Gd isotopes. Their low-lying dipole excitations, systematically investigated at the bremsstrahlung facility of the 4.3-MV Stuttgart Dynamitron accelerator, provide indications for the phase transitional behavior, including the proposed critical point candidates.
