The spin-spin relaxation rate of paramagnetic impurities in antiferromagnets
Solid State Communications, 1982Abstract The interaction between paramagnetic impurities in easy plane type antiferromagnets at finite temperatures is considered. In the framework of the diagram spin-operator technique the spin-spin relaxation rate Γ of paramagnetic impurities is investigated.

Potential Energy Surfaces and Rates of Spin Transitions
Zeitschrift für Physikalische Chemie, 2013The stability of magnetic states and the mechanism for magnetic transitions can be analyzed in terms of the shape of the energy surface, which gives the energy as a function of the angles determining the orientation of the magnetic moments. Minima on the energy surface correspond to stable or metastable magnetic states and can represent parallel ...

Reduction and destruction rates of nitroxide spin probes
Archives of Biochemistry and Biophysics, 1987A series of nitroxides was tested for rates of one-electron reduction in a chemical, a photochemical, and two biological systems by ESR assays. In all cases, piperidine and hydropyridine nitroxides were reduced consistently more rapidly than pyrroline and pyrrolidine nitroxides. Substituents on the nitroxides also affected reduction rates, although not

IEEE Journal of Quantum Electronics, 1967
An alternative to ring lasers for spin-rate sensing is proposed, which is less sensitive but potentially more compact. It consists of a two-mirror CW laser supporting a higher-order TEM pl Laguerre-Gaussian mode of the ring type, isolated by means of a uniform annular distribution of net gain.

Direction of spin axis and spin rate of the pitched baseball.
Sports biomechanics, 2007In this study, we aimed to determine the direction of the spin axis and the spin rate of pitched baseballs and to estimate the associated aerodynamic forces. In addition, the effects of the spin axis direction and spin rate on the trajectory of a pitched baseball were evaluated.

CFD Prediction for Spin Rate of Fixed Canards on a Spinning Projectile
AIP Conference Proceedings, 2011A computational study performed for spin rate of fixed canards on a spinning projectile is presented in this paper. The cancards configurations provide challenges in terms of the determination of the aerodynamic forces and moments and the flow field changes which could have significant effect on the stability, performance, and corrected round accuracy.

New results for the spin of the Eulerian triad and the logarithmic spin and rate
Acta Mechanica, 2002This work is concerned with explicit determination of spin tensor at any point of a moving continuous medium which measures the material time rate of change of orthonormal eigenvectors of symmetric Cauchy deformation tensor at the same point. Using Sylvester formula, the spin tensor is expressed as a sum of some antisymmetric tensors involving ...

Spin vectors and rates of change of wind direction
Quarterly Journal of the Royal Meteorological Society, 1988AbstractEstablished formulae for various rates of change of horizontal wind direction may be unified by a treatment in terms of the spin vector, S, of a vector field M. The spin vector measures the rate of change of direction of M, in the appropriate osculating plane, and may be defined with respect to any infinitesimal displacement in space and time ...

A spin-spin relaxation rate investigation of the gelatin ferrous sulphate NMR dosimeter
Physics in Medicine and Biology, 1994Spin-spin NMR relaxation rate in the ferrous sulphate gelatin dosimeter has been studied in terms of pH, gelatin concentration, the addition of benzoic acid, and sample size. It is demonstrated that R2 is more sensitive to changes in Fe3+ ion concentration than R1 when measuring at frequencies of 64 and 100 MHz.

Chaotic spin exchange: Is the spin non-flip rate observable?
Hyperfine Interactions, 1994If spin exchange is of the Poisson nature, that is, if the time distribution of collisions obeys an exponential distribution functionand the collision process is random, the muon spin depolarization is determined only by the spin flip rate regardless of the spin non-flip rate.
