We compare two rotationally invariant decomposition techniques on linear polarisation data: the spin-2 spherical harmonic decomposition in two opposite parities, the Eand B-mode, and the multiscale analysis of the gradient of linear polarisation, |∇P |. We demonstrate that both decompositions have similar properties in the image domain and the spatial frequency domain. They can be used as compl...

We present polarisation profiles for 48 southern pulsars observed with the new 10cm receiver at the Parkes telescope. We have exploited the low system temperature and high bandwidth of the receiver to obtain profiles which have good signal to noise for most of our sample at this relatively high frequency. Although, as expected, a number of profiles are less linearly polarised at 3.1 GHz than at...

The mid infrared polarisation properties of four Ultraluminous Infrared Galaxies (ULIRGs) have been investigated by broad band filter observations with the ISOCAM instrument on board the Infrared Space Observatory (ISO). The wavelength region from 5 to 18μm was selected where the emission from the putative torus peaks. We report detection of polarisation for all ULIRGs studied. The fractional p...

The polarisation conversion of a linear polarized electromagnetic wave incident onto a two-dimensional (2D) electron system at an angle θ is theoretically studied. We consider the 2D system located at the interface between two dielectric media with different dielectric constants. An external dc magnetic field is assumed to be directed along the normal to the 2D electron layer. In such a configu...

A suggestion is made for distinguishing 2N and 6q short range correlations within the deuteron. The suggestion depends upon observing high momentum backward nucleons emerging from inelastic electromagnetic scattering from a deuteron target. A simple model is worked out to see the size of effects that may be expected.

The empirical-phenomenological quasi-deuteron photofission description is theoretically justified within the semiclassical, intermediate statistics model. The transmutational fermion (nucleon) boson (quasi-deuteron) potential plays an essential role in the present context and is expressed in terms of thermodynamical and of microscopical quantities, analogous to those commonly used in the superf...

We introduce generalized quark and gluon distributions in the deuteron, which can be measured in exclusive processes like deeply virtual Compton scattering and meson electroproduction. We discuss the basic properties of these distributions and point out how they probe the interplay of nucleon and parton degrees of freedom in the deuteron wave function.

The Wide Angle Shower Apparatus (WASA) has been transferred from the storage ring CELSIUS (TSL, Uppsala, Sweden) to the cooler synchrotron COSY (FZ Jülich, Germany). In this presentation, the status and planning of the WASAatCOSY project are reported. The main physics aspects are rare decays of η and η' mesons and isospin violation in deuteron-deuteron interactions.
