Laser coupling to nuclei via collective electronic oscillations - A simple heuristic model study
Abstract
The induction field coupling of laser-driven collective electronic oscillations has been proposed as an interlevel transfer mechanism for a gamma-ray laser. Using a heuristic classical model for the electron oscillations, the following six general features in the model, which are conjectured to be valid for laser-induced collective oscillations are verified: (1) an enhancement of the electric field seen by the nucleus, (2) harmonic generation, (3) a generation of higher multipoles, (4) odd (even) order multipoles couple to odd (even) harmonics, (5) there exists an optimum laser intensity for each multipole order and harmonic, and (6) for a given multipole order, the optimum intensity increases with harmonic number. The relevance of these results to a proposed interlevel transfer experiment in U-235 is discussed.
