Neutron and Pair Production by Interaction of Relativistic Laser Pulses with Plasmas

Electron and bremsstrahlung photon number spectra formulas are presented for relativistic laser-plasma interactions. The relevant electron-positron and neutron productions are demonstrated by recent available laser intensities to be possible through high-energy superthermal electrons interacting with solid-targets. The result-implys that the further amelioration to optimal conditions of target is significant for increasing particle yield in photon-induced nuclear reactions.
