Spontaneous symmetry breaking in rotating nuclei

S Frauendorf - Reviews of Modern Physics, 2001 - APS
The concept of spontaneous symmetry breaking is applied to the rotating mean field of
nuclei. The description is based on the tilted-axis cranking model, which takes into account …

Quantum groups and their applications in nuclear physics

D Bonatsos, C Daskaloyannis - Progress in particle and nuclear physics, 1999 - Elsevier
Quantum algebras are a mathematical tool which provides us with a class of symmetries
wider than that of Lie algebras, which are contained in the former as a special case. After a …

New features of superdeformed bands in

B Cederwall, RVF Janssens, MJ Brinkman, IY Lee… - Physical review …, 1994 - APS
Two new features of superdeformed (SD) bands in the A≊ 190 region emerge from a study
of Hg 194 with the Gammasphere detector array. A decrease of the dynamic moment of …

Large arrays of escape suppressed spectrometers for nuclear structure experiments

CW Beausang, J Simpson - Journal of Physics G: Nuclear and …, 1996 - iopscience.iop.org
The design and performance of large arrays of escape suppressed germanium
spectrometers is described. These arrays have revolutionized the-ray spectroscopic study of …

Superdeformed rotational bands in the A∼ 140–150 mass region: A cranked relativistic mean field description

AV Afanasjev, J König, P Ring - Nuclear Physics A, 1996 - Elsevier
The cranked relativistic mean field approach is applied for a systematic investigation of
superdeformed rotational bands observed in the A∼ 140–150 mass region. The present …

Superdeformed rotational bands in the presence of Y44 deformation

I Hamamoto, B Mottelson - Physics Letters B, 1994 - Elsevier
The observation of ΔI= 4 staggering in the rotational spectra of superdeformed nuclei
suggests the occurence of Y44 deformations in the nuclear shape with associated C4v point …

staggering in octupole bands of light actinides: “Beat” patterns

D Bonatsos, C Daskaloyannis, SB Drenska… - Physical Review C, 2000 - APS
The Δ I= 1 staggering (odd-even staggering) in octupole bands of light actinides is found to
exhibit a “beat” behavior as a function of the angular momentum I, forcing us to revise the …

Mass parameters for large amplitude collective motion: A perturbative microscopic approach

EK Yuldashbaeva, J Libert, P Quentin, M Girod - Physics Letters B, 1999 - Elsevier
The adiabatic limit of the time-dependent Hartree–Fock–Bogoliubov approximation is
studied in the canonical basis for a rather wide class of collective modes. As a first step …

symmetry and bifurcation in superdeformed bands

IM Pavlichenkov, S Flibotte - Physical Review C, 1995 - APS
It is shown that the ΔI= 2 staggering effect recently discovered in superdeformed rotational
bands could be explained by a phenomenological theory of C 4 v bifurcation. In this …

Mean-field description of high-spin states

W Satuła, RA Wyss - Reports on Progress in Physics, 2004 - iopscience.iop.org
Recent high-spin observations reveal entirely new modes of collective rotational motion and
the existence of novel symmetries and spontaneous symmetry breaking phenomena …
