Nuclear Excitation by a Zeptosecond Multi--MeV Laser Pulse
arXiv:1009.6101 · doi:10.1103/PhysRevLett.106.122502
Abstract
A zeptosecond multi--MeV laser pulse may either excite a "plasma" of strongly interacting nucleons or a collective mode. We derive the conditions on laser energy and photon number such that either of these scenarios is realized. We use the nuclear Giant Dipole Resonance as a representative example, and a random--matrix description of the fine--structure states and perturbation theory as tools.
