Quantization Of Spin Direction For Solitary Waves in a Uniform Magnetic Field
… perturbation of initial data)and have nonzero spin (nonzero intrinsic angular momentum in the centre of momentum frame). In this paper we consider vector-valued solitary wave solutions to a nonlinear Klein-Gordon equation and investigate the behavior of these spinning solitary waves under the …

DIRECT DETERMINATION OF THE WEAK CHARGE OF THE PROTON VIA PARITY-VIOLATING ELECTRON SCATTERING
… was scattered by a liquid hydrogen target. The spin direction of the electron beam was switched between left and right helicity states. The cross section under both of the electron states were measured to form the parity-violating asymmetry. An asymmetry of -226.5±7.3(stat)±5.8(syst) was …

A study of the spin dependence of pion electroproduction near the [delta] region
… of 0.1 to 0.4 (GeV/c)2. By flipping the target spin direction and the electron beam helicity, the single- (beam only and target only) and double-spin (beam-target) asymmetries were constructed from the measured yields with different spin combinations, covering two kinematic setups: longitudinal …

Double spin asymmetry AL̳T̳ in charged pion production from deep inelastic scattering on a transversely polarized ³He target
… the first measurement of the beam-target double-spin asymmetry ALT for charged pion electroproduction in deep inelastic electron scattering on a transversely polarized 3He target. These data were taken between October 2008 to February 2009 using a 5.9 GeV polarized electron beam at Thomas …

Electronic Spin Coupled Nonadiabatic Dynamics
Electronic spin is one of the most fundamental observables in quantum mechanics, and in recent years, spin polarization in organic systems has received a great deal of interest. In this thesis, we investigate a novel mechanism for coupling together spin and nuclear dynamics, namely the molecular …

Measurement of target single-spin asymmetry in charged kaon electroproduction on a transversely polarized 3He target
The subject of quark transverse spin and transverse momentum distribution are two current research frontier in understanding the spin structure of the nucleons. The goal of the research reported in this dissertation is to extract new information on the quark transversity distribution and the novel …
