electric quadrupole

[i¦lek·trik ′kwä·drə‚pōl]
(electricity)
A charge distribution that produces an electric field equivalent to that produced by two electric dipoles whose dipole moments have the same magnitude but point in opposite directions and which are separated from each other by a small distance.

In this work, transition parameters have been presented such as wavelengths, oscillator strengths, and transition probabilities (or rates) for magnetic dipole (M1) and electric quadrupole (E2) transitions of low-lying levels of the spectrum in neutral boron (B I).
In this study, the transition parameters such as wavelengths, oscillator strengths, and transition probabilities for magnetic dipole (M1) and electric quadrupole (E2) transitions of low-lying levels have been calculated using multiconfiguration Hartree-Fock method within the Breit-Pauli Hamiltonian, MCHF+BP given by Fischer et al.
