Spin effects in strong-field laser-electron interactions

The interpretation of the triply differential cross sections for ionisation of inner-shell states of high-Z atoms by relativistic electrons is discussed for the case of coplanar asymmetric scattering geometry. It is demonstrated that both strong-field and relativistic interference effects lead to distinct structures in the experimental data. Elements of a similar analysis of spin asymmetries measured in experiments with transversely polarised electrons are also presented.

Using the dedicate VG-HB5 STEM microscope, the crystal structure of high Tc superconductor of YBa2Cu3O7-x has been studied via high resolution STEM (HRSTEM) imaging and nanobeam (∽3A) diffraction patterns. Figure 1(a) and 2(a) illustrate the HRSTEM image taken at 10' times magnification along [001] direction and [100] direction, respectively. In figure 1(a), a grain boundary with strong field contrast is seen between two crystal regions A and B. The grain boundary appears to be parallel to a (110) plane, although it is not possible to determine [100] and [001] axes as it is in other regions which contain twin planes [3]. Following the horizontal lattice lines, from left to right across the grain boundary, a lattice bending of ∽4° is noticed. Three extra lattice planes, indicated by arrows, were found to terminate at the grain boundary and form dislocations. It is believed that due to different chemical composition, such structure defects occur during crystal growth. No bending is observed along the vertical lattice lines.
