Multidimensionally-constrained relativistic mean-field models and potential-energy surfaces of actinide nuclei

NUCLEAR STRUCTURE ²⁴⁰Pu; calculated potential energy curves as function of deformation and truncations, three-dimensional potential energy surface contours as function of deformation around the ground state, the inner barrier, and fission isomer. ^230,232Th, ^{232,234,236,238,240}U, ^{238,240,242,244,246}Pu, ^{242,244,246,248,250}Cm, ^250,252Cf; calculated potential energy curves around the ground states and the first and second fission barriers, heights of the first second fission barriers. Multidimensionally-constrained relativistic mean-field (MDC-RMF) models, with the solution of Dirac equation in an axially deformed harmonic oscillator (ADHO) basis. Importance of nonaxial and spatial reflection asymmetric shapes in the study of potential energy surfaces and fission barriers of actinides and Superheavy nuclei. Comparison with available experimental data.
