    Notes: Abstract. Laser ablation of polyaniline in its conducting and isolating form revealed very similar ablation properties upon irradiation at 308 nm. Both types of polymer film can be structured with high resolution at high fluences. The ablation craters have sharp contours and no debris contaminates the surrounding area. At low fluences the creation of cone structures is observed. X-ray photoelectron spectroscopy reveals the carbonization of the surface upon laser ablation. As preferred decomposition sites the imine groups in doped and undoped polyaniline are identified.

    Notes: Abstract The centroid energy and the decay width of the giant monopole resonance in the unstable nucleus56Ni are predicted. The resulting 0+, ΔT=0 strength distribution, including the escape and the spreading width, displays a structure centered at around 18 MeV with the total width of about 5 MeV. We also study theM1 response in this nucleus which shows a strong isovector transition at 9.6 MeV and a weak isoscalar one at 7.5 MeV.

    Imaging-XPS/Raman investigation on the carbonization of polyimide after irradiation at 308 nm (1999)

    Notes: Abstract. The laser ablation of polyimide was studied using 308 nm laser irradiation ≤225 mJ cm-2. Confocal Raman microscopy revealed the deposition of carbon surrounding the ablation crater, which consists of amorphous carbon with some crystalline features. Inside the crater, graphitic material was detected on top of the cones, very similar to the material from cw-Ar+ ion laser irradiation. FT-Raman measurements reveal the presence of intermediates of the polyimide decomposition. Imaging-X-ray photoelectron spectroscopy confirmed the deposition of carbon material surrounding the ablation crater and showed that the oxygen and nitrogen contents of the remaining material decrease.
