Microscopic analysis of octupole shape phase transitions and critical points in neutron rich actinides

نویسندگان

چکیده

Octupole constrained energy surfaces, and spectroscopic observables of four isotopic chains of: Cm, Cf, Fm No with neutron numbers 186 N200 are analysed using a collective quadrupole - octupole Hamiltonian (QOCH). The parameters the determined by axially reflection-asymmetric relativistic Hartree-Bogoliubov calculations based on density functional DD-PC1, finite-range pairing interaction. theoretical results suggest quantum phase transitions from non-octupole to deformed shapes vibrations increasing number. 288Cm is possibly close critical point simultaneous transition spherical prolate stable configurations.

Analytic Description of Critical Point Actinides in a Transition from Octupole Deformation to Octupole Vibrations

An analytic collective model in which the relative presence of the quadrupole and octupole deformations is determined by a parameter (φ0), while axial symmetry is obeyed, is developed. The model [to be called the analytic quadrupole octupole axially symmetric model (AQOA)] involves an infinite well potential, provides predictions for energy and B(EL) ratios which depend only on φ0, draws the bo...

Shape - phase transitions in mixed parity systems and the onset of octupole deformation 1

Shape-phase transitions in mixed parity boson systems are studied using mean field theory. It is shown that without parity projection, shape transitions in mixed parity systems are very similar to those in positive parity systems, both requiring a finite interaction strength for the onset of deformation. The shape-phase diagram in mixed parity systems, however, changes significantly after parit...

Parameter - free solution of the Bohr Hamiltonian for actinides critical in the octupole mode

An analytic, parameter-free (up to overall scale factors) solution of the Bohr Hamiltonian involving axially symmetric quadrupole and octupole deformations, as well as an infinite well potential, is obtained, after separating variables in a way reminiscent of the Variable Moment of Inertia (VMI) concept. Normalized spectra and B(EL) ratios are found to agree with experimental data for Ra and Th...

Universality away from critical points in two-dimensional phase transitions.

The p-state clock model in two dimensions is a system of discrete rotors with a quasiliquid phase in a region T14. We show that, for p>4 and above a temperature T(eu), all macroscopic thermal averages become identical to those of the continuous rotor (p=infinity). This collapse of thermodynamic observables creates a regime of extended universality in the phase diagram and an emergen...
