摘要
We study the possibility for energetic nuclear collisions in a gas of molecules driven by ultra-intense and ultra-short laser pulses. The idea is to use the fact that nuclei in a molecule can be pre-aligned in front of each other and can be driven into each other by a very strong (field intensities approaching 10(23) W/cm(2)) and Ultra-short (few-femtosecond, single-cycle) laser pulse, since the nuclei of different masses will acquire different velocities when driven by the same electric field. The nuclei may collide with high kinetic energy needed to overcome the Coulomb barrier, and these collisions may lead to fusion. We have performed classical simulation of nuclear motion and a simple statistical ensemble calculation. Our results show that nuclear collisions may occur oil a sub-attosecond time scale, during which the nuclei will experience large acceleration and emit zeptosecond bursts of light.
