Are There X(5) Nuclei In The A∼80 and A∼100 Regions?

摘要: Iachello has introduced a new class of symmetries based on solutions to differential equations model phase transition and critical point behavior in nuclei. For the shape region between spherical vibrator an axial rotor dynamical symmetry is denoted X(5). A search existing data for A∼80 A∼100 regions provides tantalizing hints nuclei with X(5) character both regions.
