Paper Abstract

During the interaction of picosecond laser pulse of intensity 5 X 1018 W/cm2 with the target we observed a MeV energy proton beam, confined in a cone angle approximately 30 degree(s) and directed normal to the target surface. Laser conversion efficiency into fast ions energy (at the front side of the target) was approximately 1% (and near 5% at the rear). The simulations and optimization on ion acceleration is discussed here. The laser intensity being approximately 1019 W/cm2, nuclear reactions proceed in the target, particularly resulting in production of the (gamma) -line radiation. In light materials irradiated by the laser beam the (gamma) -photon yield reaches 10-4 number of fast ions. For nuclear excitation we used also X-ray pump from laser plasma to illuminate film mixture of KBr and Rb84. Near 104, 200 Kev decay (gamma) -photons from excited isomer nuclei can be produced per laser shot.
