2014 The cross-sections and resolving powers of the 11B(p, p’) inelastic scattering at Ep = 30.3 MeV are analyzed in the coupled-channels formalism. These calculations suggest a positive value for the quadrupole deformation 03B22 of 11B (prolate) and give the result 03B22 = + 0.52.

Nuclear Quadrupole Resonance (NQR) is effective for the detection and identification of certain types of explosives such as RDX, PETN and TNT. In explosive detection, the NQR response of certain 14N nuclei present in the crystalline material is probed. The 14N nuclei possess a nuclear quadrupole moment which in the presence of an electric field gradient produces an energy level splitting which ...

The majority of nuclei available for study in solid state Nuclear Magnetic Resonance have half-integer spin I > 1/2, with corresponding electric quadrupole moment. As such, they may couple with a surrounding electric field gradient. This effect produces anisotropic line broadening in spectra for distinct chemical species in polycrystalline solids. In Multiple Quantum Magic Angle Spinning (MQMAS...

The kinetic theories of the electric and magnetic Senftleben-Beenakker effects and of non­ resonant absorption in polar symmetric top gases are reviewed, using an expansion of the distribu­ tion function-density m atrix which includes the dipole moment operator juQ . General expressions are given for the elastic parts of all collision integrals coupling two purely angular momentum de­ pendent t...

The probing of aligned and oriented molecules or atoms by electric quadrupole and magnetic dipole transitions is described using the spherical tensor formalism. The case of cylindrical symmetry is treated explicitly. It is shown how moments of t h e initial angular momentum distribution up to rank 4 are obtainable using electric quadrupole radiation. The interference between electric quadrupole...

We report experimental investigations of a single-ion optical frequency standard based on Yb+. The ion is confined in a cylindrically symmetric radiofrequency Paul trap. The reference transition is the S1/2 F=0 – D3/2 F =2 electric quadrupole transition at 688 THz. Using a differential measurement scheme, we determine the shift of the reference transition frequency that occurs due to the intera...

We use the nuclear density functional theory to determine electric quadrupole and magnetic dipole moments in all one-particle one-hole neighbours of eight doubly magic nuclei. align angular momenta along intrinsic axial-symmetry axis with broken time-reversal symmetry, which allows us explore fully self-consistent charge, spin, current polarisation. Spectroscopic are determined for symmetry-res...

The filled skutterudite compound PrOs4Sb12 exhibits superconductivity below a critical temperature Tc = 1.85 K that develops out of a nonmagnetic heavy Fermi liquid with an effective mass m∗ ≈ 50 me, where me is the free electron mass. Analysis of magnetic susceptibility, specific heat, electrical resistivity and inelastic neutron scattering measurements within the context of a cubic crystallin...
