摘要

Using the Brink-Axel hypothesis we derive the rate R for nuclear dipole excitation by a laser pulse carrying N 1 photons with average energy h omega(0) approximate to 5 MeV. As expected R proportional to (h omega(0))(3). The rate is also proportional to the aperture a of the laser pulse. Perhaps less expected is the fact that R. N, irrespective of the degree of coherence of the laser pulse. The expression for R, derived for a nearly stationary laser pulse, is valid also for short times and can, thus, be used in simulations via rate equations of multiple nuclear dipole excitations by a single pulse. The explicit dependence of R on the parameters of the laser pulse and on nuclear parameters given in the paper should help to optimize experiments on laser-nucleus reactions.
