Study on Focusing High Current Electron Beams with Quadrupole Magnets in LIA
Aimed to obtain small-sized beam spots, the focusing characteristics of high current electron beams generated by linear induction accelerators (LIA) with the quadrupole magnets were studied in this paper. The main factors which influence the minimum beam

Investigations of Ra$^+$ properties to test possibilities of new optical frequency standards [PDF]
The present work tests the suitability of the narrow transitions $7s \ ^2S_{1/2} \to 6d ^2D_{3/2}$ and $7s ^2S_{1/2} \to 6d ^2D_{5/2}$ in Ra$^+$ for optical frequency standard studies. Our calculations of the lifetimes of the metastable $6d$ states using

Coupled–Channels Analyses For Heavy–Ion Fusion Reactions of 16O+92Zr,144,148Sm Systems
We study in detail the fusion reaction of 16O with 92Zr and 144,148Sm at sub-barrier energies with coupled-channels framework using the error function potential for the nuclear potential.

Accurate long-range coefficients for two excited like isotope He atoms: He($2 ^1P$)--He($2 ^1P$), He($2 ^1P$)--He($2 ^3P$), and He($2 ^3P$)--He($2 ^3P$) [PDF]
A general formalism is used to express the long-range potential energies in inverse powers of the separation distance between two like atomic or molecular systems with $P$ symmetries.

Vector potential and stored energy of a quadrupole magnet array [PDF]
The vector potential, magnetic field and stored energy of a quadrupole magnet array are derived. Each magnet within the array is a current sheet with a current density proportional to the azimuthal angle 2/spl theta/ and the longitudinal periodicity (2m-1)/spl pi//L. Individual quadrupoles within the array are oriented in a way that maximizes the field

Perturbative Approach to the Gravitational Lensing by a Non-spherically Distorted Compact Object
We investigate the gravitational lens effect caused by a non-spherically distorted compact object. The non-spherical property of the gravitational potential is modeled by a quadrupole moment. Under the assumption that the quadrupole contribution is small,
