In the process of the interaction of Ultra Intense Laser UIL beams with Plastic targets, it was proved to efficiently bunch accelerated Hydrogen ions [1, 2]. The efficient Radiation Pressure Acceleration (RPA) mechanism [3, 4, 5, 6] for laserbased ion acceleration, could explain the production of bunches of solid state density through the hole-boring mode [7]. Allowing such dense bunches of Hydrogen ions i.e. protons to impinge on a second thicker Borated Polyethylene target would easily result in fusion of the UIL Laser accelerated protons with the B11 nuclei, resulting in highly excited fused carbon nuclei. Such fused species would soon disintegrate by evaporating light particles or by fission into relatively lighter fragments. In this scenario the first target could well be polyethylene foil of thickness less than 500 μm and would be considered the source of the accelerated Hydrogen ions or protons. -The second target would be expected to contain C12 compound nuclei by p1 + B11 ----. C 12* fusion as well as lighter nuclei due to fission of C 12* nuclei. In the following we propose to estimate the possibility of producing important non emitting neutron nuclei such as B isotopes and or Alpha particles in the second Borated polyethylene target. Simulation of fusion, followed by particles evaporation, is elaborated applying Mont Carlo code PACE-4 [8]. In this Contest a planned experiment will be briefly introduced, where the production of such nuclei and the experiment to measure their properties will be elaborated.
