Nuclear structure study of even-even 24-42Si isotopes using Skyrme - Hartree - Fock and Hartree - Fock - Bogolyubov methods

Ядерна фізика та енергетика, 2020
The nuclear ground-state properties and the nuclear deformation of some even-even Silicon isotopes have been investigated. The spherical Skyrme-Hartree-Fock method that includes Hartree-Fock calculations in addition to several common Skyrme ...

Constraining quadrupole deformations with relativistic effects

European Physical Journal C: Particles and Fields
We investigate two general relativistic effects—namely, the Shirokov and Shapiro effects—within the framework of the Zipoy–Voorhees spacetime (q-metric), which generalizes the Schwarzschild solution by incorporating a quadrupole moment.

Nuclear collective motion with a coherent coupling interaction between quadrupole and octupole modes

, 2006
A collective Hamiltonian for the rotation-vibration motion of nuclei is considered, in which the axial quadrupole and octupole degrees of freedom are coupled through the centrifugal interaction.

Analysis of transverse beam stabilization with radio frequency quadrupoles

Physical Review Accelerators and Beams, 2017
A radio frequency (rf) quadrupole has been considered as a potential alternative device for Landau damping in circular hadron colliders. The objective of this study is to benchmark and confirm its stabilizing effect predicted by stability diagram theory ...

Nuclear Quadrupole Hyperfine Structure in HC14N/H14NC and DC15N/D15NC Isomerization: A Diagnostic Tool for Characterizing Vibrational Localization

, 2008
Large-amplitude molecular motions which occur during isomerization can cause significant changes in electronic structure. These variations in electronic properties can be used to identify vibrationally-excited eigenstates which are localized along the ...

Classical Analysis of Phenomenological Potentials for Metallic Clusters

, 1994
The classical trajectories of single particle motion in a Wodds-Saxon and a modified Nilsson potential are studied for axial quadrupole deformation. Both cases give rise to chaotic behaviour when the deformation in the Woods-Saxon and the l**2 term in ...
