Pseudo-symplectic model for strongly deformed heavy nuclei
An extension of the strong-coupled pseudo SU(3) model, which is a scheme that has found application in the study of superdeformed bands in heavy nuclei, is introduced. The theory includes multiple inter-shell excitations of the monopole and quadrupole type. It is an extension to heavy (A ≳ 100) nuclei of the microscopic collective model which applies for light (A ≲ 28) systems. Because the scheme has a Sp(3,R) ⊃ SU(3) group theoretical structure, it is called the pseudosymplectic model. A boson expansion for the model hamiltonian is given and results for an application of the theory to 238U presented. © 1991.
