Tilted Rotation and Wobbling Motion in Nuclei
W. D. Heiss, R. G. Nazmitdinov
The self-consistent harmonic oscillator model including the three-dimensional cranking term is extended to describe collective excitations in the random phase approximation. It is…
Tri-axial Octupole Deformations and Shell Structure
W. D. Heiss, R. G. Nazmitdinov, R. A. Lynch
Manifestations of pronounced shell effects are discovered when adding nonaxial octupole deformations to a harmonic oscillator model. The degeneracies of the quantum spectra are in…
Shell Effects in Mesoscopic Systems
R. G. Nazmitdinov, W. D. Heiss
The main aim of the results presented here is to demonstrate and analyse the importance of shell effects in nuclei, metallic clusters and quantum dots.
Nuclear Shell Structure and Chaotic Dynamics in Hexadecapole Deformation
W. Dieter Heiss, Rashid G. Nazmitdinov, Stefanel Radu
The effect of an axially symmetric hexadecapole term is investigated in a strongly deformed quadrupole potential. While the system is nonintegrable and shows significant chaotic be…
Shell Structures and Chaos in Deformed Nuclei and Large Metallic Clusters
W. Dieter Heiss, Rashid G. Nazmitdinov, Stefanel Radu
A reflection-asymmetric deformed oscillator potential is analysed from the classical and quantum mechanical point of view. The connection between occurrence of shell structures and…
