D J Ives, National Physical Laboratory UK. ([email protected]) Abstract Many of the sources used in optical fibre systems are highly polarised and thus for highly accurate power measurements the polarisation dependent response (PDR) of the power meter becomes an important parameter. The use of Optical Spectrum Analysers (OSA) to test components and measure the relative powers in WDM systems ...

Two fundamental laser physics phenomena--dissipative soliton and polarisation of light are recently merged to the concept of vector dissipative soliton (VDS), viz. train of short pulses with specific state of polarisation (SOP) and shape defined by an interplay between anisotropy, gain/loss, dispersion, and nonlinearity. Emergence of VDSs is both of the fundamental scientific interest and is al...

A key aspect of animal development is the appropriate polarisation of different cell types in the right place at the right time. Such polarisation is often precisely coordinated relative to the axes of a tissue or organ, but the mechanisms underlying this coordination are still poorly understood. Nevertheless, genetic analysis of animal development has revealed some of the pathways involved. Fo...

The existing experimental data for the deuteron charge radius are discussed. The data of elastic electron scattering are inconsistent with the value obtained in a recent atomic physics experiment. Theoretical predictions based on a nonrelativistic description of the deuteron with realistic nucleon-nucleon potentials and with a rather complete set of meson-exchange contributions to the charge op...

A new design is presented for a time-ofight neutron spectrometer that uses a shaped scattering foil to generate deuteron recoils. It is shown that the number of recoils can be substantially increased by utilizing a three-dimensional, deuterated scattering foil in the shape of an ellipsoid, which maintains the time-ofight dispersion present originally in the neutrons. The time-integrated neutron...

Two-proton and two-deuteron correlations have been studied in the target fragmentation region of central Pb+Pb collisions at 158 A GeV. Protons and deuterons were measured with the Plastic Ball spectrometer of the WA98 experiment at the CERN SPS. The results of one-dimensional and multi-dimensional analyses using both the Bertsch-Pratt and Yano-Koonin-Podgoretsky parameterizations of the two-pa...

A Monte Carlo light scattering code incorporating aligned non-spherical particles is described. The major effects on the flux distribution, linear polarisation and circular polarisation are presented, with emphasis on the application to Young Stellar Objects (YSOs). The need for models with non-spherical particles in order to successfully model polarisation data is reviewed. The ability of this...

We review1 some recent results for elastic electron deuteron scattering (deuteron form factors) and photodisintegration of the deuteron, with emphasis on the recent high energy data from Jefferson Laboratory (JLab). DEUTERON WAVE FUNCTIONS AND FORM FACTORS Calculations of deuteron form factors and photo and electrodisintegration to the NN final state require a deuteron wave function. The best n...
