Electric quadrupole transitions of the Bohr Hamiltonian with the Morse potential [PDF]
Eigenfunctions of the collective Bohr Hamiltonian with the Morse potential have been obtained by using the Asymptotic Iteration Method (AIM) for both gamma-unstable and rotational structures.

Discussion on Design Ideas of Quadrupole Field of Mass Spectrometry [PDF]
The mass analyzer based on quadrupole field theory, including quadrupole and ion trap, control and screen ions by a non-magnetic, alternating electric field, which was the first proposed by Professor Paul in 1953.

Quasithermalization of collisionless particles in quadrupole potentials [PDF]
We analyze several puzzling features of a recent experiment with a noninteracting gas of atoms in a quadrupole trap. After an initial momentum kick, the system reaches a stationary, quasi-thermal state even without collisions, due to the dephasing of individual particle trajectories.

Effects of electric quadrupole interactions with tunable atomic mirrors
Recent studies have involved electric quadrupole effects in atoms interacting with the evanescent mode. This type of surface mode is usually produced by the total internal reflection in a dielectric-vacuum atz=0, and its intensity distribution is very ...

Enhancement of specular behavior in atom mirrors with quadrupole-active transitions
Modern studies have confirmed the possibility of making atomic mirrors using quadrupole-active atomic transition evanescent waves. The reflection process has been shown to be enhanced to approach specular behavior in several ways.

Effect of space charge potential on the behavior of confined gaseous 238UF6 ions in paul ion trap [PDF]
This paper examined the behavior of confined 238UF6 gaseous ions in Paul’s quadrupole mass spectrometer under the influence of the field induced by the RF and DC potential applied to the end cap and ring electrodes and space charge potential, based on ...

Enhanced quadrupole effects for atoms in surface spiral beams with a thin dielectric waveguide
Recently, some physical research has recognized the coupling of optical phase singularity light with quadrupole-active atomic transitions. We show that a Laguerre-Gaussian beam, when completely internally reflected at the dielectric/vacuum interface, can
