Semi-classical and boson descriptions of scissors states
A. A. Raduta, C. M. Raduta, R. Poenaru +1
A two interacting rotors Hamiltonian is alternatively treated semi-classically and by a Dyson boson expansion method. The linearized equations of motion lead to dispersion equation…
Semiclassical Features of Wobbling and Chiral Properties in Nuclei
Apolodor Aristotel Raduta, Cristian Mircea Raduta, Robert Poenaru
A semiclassical approach is used to describe the wobbling and chiral motion in even-even and odd-even nuclei The trial function involved in the variational equation for the quantal…
Simultaneous description of wobbling and chiral properties in even-odd triaxial nuclei
C. M. Raduta, A. A. Raduta, R. Poenaru +1
A particle-triaxial rigid core Hamiltonian is semi-classically treated. The coupling term corresponds to a particle rigidly coupled to the triaxial core, along a direction that doe…
New results about the canonical transformation for boson operators
C. M. Raduta, A. A. Raduta
The Bogoliubov transformation for a monopole boson induces an unitary transformation connecting the Fock spaces of initial and correlated boson-s. Here we provide a very simple met…
A new boson approach for the wobbling motion in even-odd nuclei
A. A. Raduta, C. M. Raduta, R. Poenaru
A triaxial core rotating around the middle axis, i.e. 2-axis, is cranked around the 1-axis, due to the coupling of an odd proton from a high j orbital. Using the Bargmann represent…
A new approach for the wobbling motion in the even-odd isotopes Lu
A. A. Raduta, R. Poenaru, C. M. Raduta
A new interpretation for the wobbling bands in the even-odd Lu isotopes is given within a particle-triaxial rotor semi-classical formalism. While in the previous papers the bands T…
