      abstract     = {The spatial structure of the Kalpha emission from Ti
                      targets irradiated with a high intensity femtosecond laser
                      has been studied using a two-dimensional monochromatic
                      imaging technique. For laser intensities I<5x10(17) W/cm(2),
                      the observed spatial structure of the Kalpha emission can be
                      explained by the scattering of the hot electrons inside the
                      solid with the help of a hybrid particle-in-cell/Monte Carlo
                      model. By contrast, at the maximum laser intensity
                      I=7x10(18) W/cm(2) the half-width of the Kalpha emission was
                      70 mum compared to a laser-focus half-width of 3 mum.
                      Moreover, the main Kalpha peak was surrounded by a halo of
                      weak Kalpha emission with a diameter of 400 mum and the
                      Kalpha intensity at the source center did not increase with
                      increasing laser intensity. These three features point to
                      the existence of strong self-induced fields, which redirect
                      the hot electrons over the target surface.},
