A Monte Carlo simulation of electron transport in electric and magnetic fields was performed to analyze experimental data of the electron temperature T e and electron number density n e measured in a magnetic neutral loop discharge (NLD) plasma driven in Ar at 0.13 Pa. T e and n e in the vicinity of the substrate holder were measured with a triple probe, and their radial profiles had peaks at different radial positions.The simulation reproduced these peak positions well under the chosen boundary condition that the electron reflectivity of the side wall was lower than that of the reactor ceiling and the substrate holder. It was explained that the T e peak was formed by high-energy electrons transported from the neutral loop along a separatrix of the quadrupole magnetic field and that the n e peak consisted of electrons undergoing reciprocating motion between the reactor ceiling and the substrate.
A maximal state of spin polarisation of a spin-1 system with all eight degrees of freedom (namely, three distinct axes and two non-zero scalars) is realised when a spin-I nucleus with nonzero electric quadrupole moment is embedded in a suitable crystal lattice generating an electric quadrupole field and is exposed to an external constant magnetic field whose direction does not coincide with any of the principal axes characterising the electric quadrupole field. In the absence of the magnetic field only five of the eight degrees of freedom (i.e., two distinct axes and a nonzero scalar) are realised if the asymmetry parameter v # 0. If q=O the two axes coalesce. This suggestion is made to stimulate experimental efforts to produce polarised multiaxial spin-1 targets.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
