On the asymptotic methods for nuclear collective models
A. C. Gheorghe, A. A. Raduta
Contractions of orthogonal groups to Euclidean groups are applied to analytic descriptions of nuclear quantum phase transitions. The semiclassical asymptotic of multipole collectiv…
A solvable model which has X(5) as a limiting symmetry and removes some inherent drawbacks
A. A. Raduta, A. C. Gheorghe, P. Buganu +1
Solvable Hamiltonians for the and intrinsic shape coordinates are proposed. The eigenfunctions of the Hamiltonian are spheroidal periodic functions, while the Hamiltoni…
Remarcs on the shape transition from spherical to deformed gamma unstable nuclei
A. A. Raduta, A. C. Gheorghe, Amand Faessler
Energies and transition probabilities for low lying states in Ba and $^{104$Ru were calculated within a hybrid model.The ground and the first states are described alt…
New results for the missing quantum numbers labeling the quadrupole and octupole boson basis
A. Gheorghe, A. A. Raduta
The many -pole boson states, with , realize the irreducible representation (IR) for the group reduction chains $SU(2k+1)\supset R_{2k+1}\supset R_3…
