Laser-Assisted Photonuclear Effect in Halo-Nuclei — •Anis Dadi and Carsten Müller — Max-Planck-Institut für Kernphysik Saupfercheckweg 1, D-69117 Heidelberg

The emission of a proton from a halo nucleus by absorption of a high-energy photon in the presence of a strong optical laser beam is studied. It is shown that the assisting laser field modifies the properties of the photonuclear effect in a characteristic way. We investigate the energy distribution of the photoproton in terms of the number of absorbed laser photons, as well as the angular proton distribution as a function of the polar emission angle. The dependencies on the photon energy, the laser polarization, and the field geometry are discussed as well.
