Abstract :
We report on the generation of protons with energies of 5.5 MeV when irradiating an H2O nano-wire layer grown on a sapphire plate with an intensity of 5×1017 W/cm2. A theoretical model is suggested in which plasma near the tip of the wire is subject to enhanced electrical fields and protons are accelerated to several MeVs.
