The Xe 5s nondipole photoelectron parameter gamma is obtained experimentally and theoretically from threshold to approximately 200 eV photon energy. Significant nondipole effects are seen even in the threshold region of this valence shell photoionization. In addition, contrary to previous understanding, clear evidence of interchannel coupling among quadrupole photoionization channels is found.
Tae spin-lattice relaxation of deuterated methyl groups, which is exponential at high temperatures, becomes non-exponential at low temperatures as evidence of the coupling between the Zeeman and tunneling systems. The dominant relaxation is considered to be the quadrupole interaction. Experimental results at liquid nitrogen and liquid helium temperatures support the theoretical model.
The betatron coupling is one of the most important parameters of storage rings for high brilliant light source. By the precise alignment of the magnets [1] and the proper COD correction [2], the SPring-8 storage ring succeeded in achieving the very small linear betatron coupling without skew quadrupole corrector magnets. To prove this fact, we study the betatron coupling of the SPring-8 storage...
The quadrupole coupling constants in solids usually depend on temperature (see f.e. Ref. [1 — 8 ]). This can be explained by the change of vibration amplitudes of molecules, but the influence of the volume expansion on the electric field gradient has also to be taken into account [4], For 185Re and 187Re in some peirhenates NQR measurements have been reported [9 — 16]. With the exception of NH ...
The coupling of the high-lying dipole mode to the low-lying quadrupole modes for the case of deformed γ-unstable nuclei is studied. Results from the geometrical model are compared to those obtained within the dipole boson model. Consistent results are obtained in both models. The dipole boson model is treated within the intrinsic frame, with subsequent projection onto the laboratory frame. As a...
Cyanobenzenes have recently been suggested as good candidates for the detection of aromatic molecules in interstellar space [1–3], partly due to their large dipole moments. The simplest molecule from this class is benzonitrile (C6H5CN), which might be detectable, for example, in the proto-planetary nebula CRL 618 [1, 2]. These predictions are based on an assumed abundance of 10 and a dipole mom...
Precise values are reported for a quite large (95)Mo quadrupole coupling and an unusually large (95)Mo chemical shift anisotropy in MoS(2), values that have been retrieved by analysis of a well-resolved, highly complex 14.1 T (95)Mo MAS NMR spectrum displaying both the central and satellite transitions.
