structure of molecules by gaining insight into nuclear interactions. Used in conjunction with theoretical calculations, NMR has the potential to elucidate these nuclear interactions and how they affect structure, bonding and dynamics on a molecular scale. The first two projects presented herein study the peroxide explosive BLOCKIN BLOCKIN hexamethylene BLOCKIN BLOCKIN triperoxide BLOCKIN BLOCKI...

Transverse quadrupole wake fields exist whenever the beam is not round, and therefore in an alternating gradient focusing system these fields cannot be eliminated. As a result, these fields represent a potential limitation on high intensity linac performance. In this note we calculate the magnitude of quadrupole wake field effects for the SLAC linac.

Scattering of cosmic microwave background (CMB) radiation in galaxy clusters induces a polarization signal proportional to the CMB quadrupole anisotropy at the cluster’s location and look-back time. A survey of such remote quadrupole measurements provides information about large-scale cosmological perturbations. This paper presents a formalism for calculating the correlation function of remote ...

This study examines the dynamic feedbacks generated from synoptic eddies that contribute to maintenance and propagation of intraseasonal North Atlantic Oscillation (ISNAO) which has significant 20?60-day variability features clearly westward slightly northward propagations. The ISNAO-related eddy-vorticity fluxes induced forcing positive in-phase feedback upstream ISNAO. Due accumulated shearin...

We report the transport of magnetically trapped cold atoms over a large distance. Atoms are captured in a magneto-optical trap ~MOT! and loaded into a magnetic quadrupole trap. The quadrupole potential is then moved over a distance of 33 cm into an ultra-high-vacuum ~UHV! chamber using a chain of quadrupole coils. By running suitable currents through the quadrupole coil pairs the trapping geome...

The two neutrino and neutrinoless double beta decay of Zr, Mo, Ru, Pd, Te and Nd isotopes for the 0 → 0 transition is studied within the PHFB framework along with an effective two-body interaction consisting of pairing, quadrupole-quadrupole and hexadecapole-hexadecapole correlations. It is found that the effect of hexadecapolar correlations can be assimilated substantially as a renormalization...

Two-dimensional exchange Cl nuclear quadrupole resonance spectroscopy for studies of the CCl3-group reorientation processes in hexachloroethane and chloral hydrate has been applied. Experimental results were interpreted on the basis of the 2D exchange nuclear quadrupole resonance theory, which takes into account the off-resonance irradiation. It has been demonstrated that 2D nuclear quadrupole ...
