The relationship between the level of spin polarisation caused by Un-ruh radiation as calculated by Bell and Leinaas and that obtained from the Derbenev–Kondratenko formalism is explained.

Polarised quark distributions are extracted from semi-inclusive deep inelastic scattering data, which include the additional detection of a leading hadron to providestatisticaìàvour-tagging'. Results are combined from both proton and`neutron' targets to isolate the contributions to the nucleon spin of the individual quark avours, including the sea quarks. Spin asymmetries in the semi-inclusive ...

Abstract This chapter focuses on the introduction and discussion of electron polarization. In addition to gyromagnetic ratio, most different character electrons compared protons is that radiate electromagnetic energy in a circular accelerator. A very small correction has be applied spin flip account for synchrotron radiation. The instantaneous probabilities, up down up, can build beam polarizat...

the magnetisation and electron spin resonance (esr) spectrum of two specimens of tetrahedral amorphous carbon (ta-c), deposited from a filtered cathodic arc, were measured over a wide temperature range. the magnetisation was found to consist of superparamagnetic, paramagnetic and diamagnetic contributions. the superparamagnetic contribution resembled that recently found in carbon prepared from ...

Stability of the ;-; stacking interactions in the substituted-coronene||cyclooctatetraene complexes wasstudied using the computational quantum chemistry methods (where || denotes ;–; stackinginteraction, and substituted-coronene is coronene which substituted with four similar X groups; X =OH, SH, H, F, CN, and NO). There are meaningful correlations between changes of geometricalparameters and t...
