Development of spin-polarized ion scattering spectroscopy.

Layer-dependent magnetic properties at Fe surfaces using spin-polarized electron emission spectroscopy (SPEES)

We have studied the angle-resolved energy distribution of spin-polarized electrons emitted during ion-surface scattering. At clean Fe surfaces, electron spin polarization values (ESP) of up to 48% are found. Varying the scattering angle of the ions from 1 ° to 45 °, we find that the layer-dependent, average ESP at the topmost surface layer is enhanced by 32% compared to that of the bulk and tha...

Nuclear Reactions with Polarized Heavy Ions(1)

The development of the field since the Osaka conference is desribed c nce tra 'ng entirely on experiments with polarized ion beams presently available g i 9 , 1 1 ( L , L , Na). Their internal structure is sufficiently different to demonstrate the richness of the field. Main topics are: Coulomb scattering of aligned projectiles which deliver new information on dynamical electric mu1 tipole mome...

Psu/th/118 Spin in Perturbative Qcd; Coherent Hard Diffraction 1

I briefly review: (a) some recent developments in the theory of hard scattering in QCD with polarized beams, and (b) coherent hard diffraction (that is, hard scattering in diffractive events, with the Pomeron behaving in an apparently point-like fashion). 1. Polarized Hard Scattering Interest in polarized hard scattering has increased recently. An important reason is that it appears feasible to...

Transverse Spin Effects at COMPASS

The measurement of transverse spin effects in semi-inclusive deepinelastic scattering (SIDIS) is an important part of the COMPASS physics program. In the years 2002-2004 data was taken by scattering a 160GeV/c muon beam off a transversely polarized deuteron target. In 2007, additional data was collected on a transversely polarized proton target. New preliminary results for the Collins and Siver...
