Nuclear Spin Relaxation within Interstellar Grains
We identify a new mechanism of internal dissipation of rotational kinetic energy in spinning dust grains, arising from the reorientation of nuclear angular momentum, e.g., spins of protons. Grain rotation induces magnetization of the nuclear spin system, with net alignment of nuclear spins parallel to the grain angular velocity. When the grain does not rotate around a principal axis, the nuclea...
متن کاملAll-optical measurement of nuclear-spin relaxation
Nuclear-spin relaxation rates are usually measured by pulsed radio frequency excitation of nuclear-spin transitions. When the number of spins is too small for direct detection with conventional nuclear-magneticresonance spectrometers, pulsed excitation may be combined with optical detection of the nuclear spins for increased sensitivity. Here we demonstrate that such measurements can also be do...
متن کاملNuclear spin relaxation in glassy ionic conductors
The nuclear spin relaxation behaviour in disordered ionically conducting materials is ascribed to a mechanism based on diffusion-controlled relaxation. In this targetdiffusion model, relaxation is assumed to occur at interstitialcy sites, triggered by the arrival of diffusing ions. The dependence of the spin-lattice relaxation rate on the temperature, Larmor frequency and ionic concentration ca...
متن کاملNuclear Spin Relaxation of Polycrystalline Xenon
Through spin exchange optical pumping it is possible to achieve upwards of nuclear spin polarization in Xe with an NMR signal enhancement of some orders of magnitude over typical thermal signals Hyperpolarized Xe has thus found application in several leading edge technologies At T and K the characteristic relaxation time of enriched polycrystalline Xe Xe Xe is well over hrs su cient for long te...
متن کاملNuclear spin relaxation in liquids and gases
The aim of this report is to cover the progress of work in the field of magnetic relaxation and self-diffusion in liquids and gases over a period of twelve months from June 2005 to May 2006, and is a continuation of the report given last year. As in previous periods, this review is limited to work on comparatively simple liquids and solutions of physico-chemical and chemical interest, as public...
