The onset of chaos with a quadrupole-quadrupole interaction [PDF]
Il Nuovo Cimento A, 1995 The transition from order to chaos in atomic nuclei has been studied analytically and numerically using a quadrupole--quadrupole residual interaction. This interaction leads to chaotic behaviour, but the critical energy $E_C\simeq 12.6$ MeV, corresponding to the onset of chaos, is higher than that of the experimental one.

Multiplexing Quadrupole and Ion Trap Operation Modes on a “Brick” Miniature Mass Spectrometer
Molecules, 2023 Although a quadruple mass analyzer and an ion trap mass analyzer have complementary analytical features, they usually have different geometries, operational modes, and electronic control systems.

Systematics of the Quadrupole–Quadrupole Interaction and Convergence Properties [PDF]
Annals of Physics, 1999 Our main concern in this work is to show how higher shell admixtures affect the spectrum of a Q.Q interaction. We first review how, in the valence space, the familiar SU(3) result for the energy spectrum can be obtained using a coordinate space Q.Q interaction rather than the Elliott one which is symmetric in r and p.

Status of injection transport beam line at kernfysish versneller institute [PDF]
Nuclear Technology and Radiation Protection, 2004 At Kernfysisch Versneller Institute, optical properties of injection transport beam were studied. Measurements of beam size and emittance determined by "varying quadrupole method" are compared with calculations including fringe fields up to the third ...

Circular Geodesics in a New Generalization of q-Metric
Universe, 2022 This paper introduces an alternative generalization of the static solution with quadrupole moment, the q-metric, that describes a deformed compact object in the presence of the external fields characterized by multipole moments.

MODEL OF THE FLAT FAIRING ANTENNA DIELECTRIC LAYER WITH AERODYNAMIC HEATING
Informatyka, Automatyka, Pomiary w Gospodarce i Ochronie Środowiska, 2023 To protect the antenna systems of modern aircraft, radio-transparent dielectric fairings are widely used. At low flight speeds, when designing and evaluating the characteristics of the fairing-antenna, it is assumed that the dielectric constant is a ...

Compact, Broadband, and Omnidirectional Antenna Array for Millimeter-Wave Communication Systems
Journal of Microwaves, Optoelectronics and Electromagnetic Applications, 2021 In this paper, a millimeter-wave printed quadrupole antenna is proposed. It consists of two symmetric printed dipoles that make the quadrupole radiating power omnidirectionally.

Two-dimensional three-body quadrupole–quadrupole interactions [PDF]
Journal of Physics B: Atomic, Molecular and Optical Physics, 2021 Abstract The interactions between dipoles are called dipole–dipole interactions. One type of dipole–dipole interaction is van der Waals interaction. Similar to van der Waals interactions, the interactions between quadrupoles are called quadrupole–quadrupole interactions. Atoms can be treated not only as dipoles but also as quadrupoles.

Accretion disks around a mass with quadrupole QUADRUPOLE
Bulletin of Kazakh Leading Academy of Architecture and Construction, 2021 In this work, we consider the exterior static axisymmetric gravitational of compact objects. We investigate the properties of the q-metric which is the simplest generalization of the Schwarzschild solution that contains a quadrupole parameter. The geodesic line equation is derived from the field equations and the orbits of the test particle are ...
