متن کاملParity shift and beat staggering structure of octupole bands in a collective model for quadrupole–octupole deformed nuclei
We propose a collective model formalism which describes the strong parity shift observed in low-lying spectra of nuclei with octupole deformations together with the fine rotational band structure developed at higher angular momenta. The parity effect is obtained by the Schrödinger equation for oscillations of the reflection asymmetric (octupole) shape between two opposite orientations in an ang...
متن کاملHexadecapole interaction and the △I=4 staggering effect in rotational bands
A role of the multipole interaction in the description of the △I=4 staggering phenomenon is investigated in a model consisting of a single-j shell filled by identical nucleons. Exact diagonalization of the quadrupole-plushexadecapole Hamiltonian shows that the hexadecapole-hexadecapole interaction can produce a △I=4 periodicity in the yrast sequence. PACS numbers: 21.10.Re, 21.30.+y, 21.60.Cs
متن کاملHexadecapole Approximation in Planetary Microlensing
The frequency of microlensing planet detections, particularly in difficult-tomodel high-magnification events, is increasing. Their analysis can require tens of thousands of processor hours or more, primarily because of the high density and high precision of measurements whose modeling requires time-consuming finitesource calculations. I show that a large fraction of these measurements, those th...
متن کاملTri-axial Octupole Deformations and Shell Structure
The remarkable regularity of rotational spectra of superdeformed nuclei has prompted many investigations into the contribution of higher multipoles on the formation of shell structure [1]. Related questions have arisen for other mesoscopic systems. In particular, it appears that octupole deformation has the same importance for two-dimensional systems like quantum dots and surface clusters [2] a...
