Transition quadrupole moments of superdeformed states in194Pb

Zeitschrift f�r Physik A Hadrons and Nuclei, 1992
Lifetimes of superdeformed states in194Pb were measured by the Doppler-shift attenuation method. Quadrupole moments around 20 eb, that are constant over the observed frequency range, are derived. The results rule out large centrifugal stretching effects.

RADIAL MATRIX ELEMENT FOR THE QUADRUPOLE TRANSITION WITH THE MORSE POTENTIAL

Canadian Journal of Physics, 1952
A general formula for the radial part of the matrix element for the quadrupole transition with the Morse potential is derived using standard methods of analysis. The same methods can also be used to derive an expression for the radial part of the dipole transition matrix element.

QUADRUPOLE STRENGTH IN THE N→Δ TRANSITION

2001
The possibility of nucleon deformation raised more than 20 years ago 1 still remains an open one. The presence of resonant quadrupole amplitudes in the transition to the only isolated excited state of the nucleon is regarded as the definitive signature of deviation from the simplistic spherical models of the nucleon and/or the delta.

Transition quadrupole moments in the superdeformed band of 40Ca

2003
The transition quadrupole moments Qt for the superdeformed band in 40Ca have been determined through thin-target Doppler-shift attenuation analyses. A best-fit value of Qt = 1.30 ± 0.05 e b is obtained when a single value is assumed for the entire band.

Electric quadrupole transitions in LiI, BeII, BIII

Journal of Quantitative Spectroscopy and Radiative Transfer, 1975
Abstract Theoretical values of the weighted oscillator strengths for different electric quadrupole transitions of LiI, BeII and BIII have been calculated using analytic Hartree-Fock wave functions. An appropriate hypervirial check has been made to assess the accuracy of the values. Some interesting features of the hypervirial operator are discussed.

Ozone 17O quadrupole transitions in chloroform glass

Journal of Molecular Structure, 1980
Abstract 17O pure quadrupole transitions have been detected in ozone dissolved in a chloroform glass at 1.5°K with a field-cycling proton double resonance spectrometer. A broad resonance centered at 5.50 MHz is tentatively assigned to unresolved v 3 2 ↔ 1 2 and v 5 2 ↔ 3f 2 transitions, from terminal oxygen atoms. The assignment

Electric quadrupole transitions in the beryllium isoelectronic sequence

Astrophysics and Space Science, 1983
Electric quadrupole transition probabilities for transitions between the 2s2, 2s2p, and 2p2 states in the beryllium isoelectronic sequence are evaluated using configuration interaction wavefunctions for 6≤Z≤26. It is found that the contribution from the electric quadrupole transitions is negligible and will not be an important process in any laboratory
