Abstract

Energy transfer processes in a simple single particle coupled nuclear-electron model interacting with an intense laser field are studied. In our model, an excited valence proton is bound as an independent particle in a Woods-Saxon potential—its dynamics are characteristic of nuclear motion in the Blatt and Weisskopf single-particle approximation. The electron is bound to the nu clear core in a nonrelativistic treatment by a Coulomb potential—its dynamics are characteristic of single-particle electronic transitions. Initial conditions for the classical trajectories are chosen to be states of the separable Hamiltonian, and the Bohr quantization condition is applied. The spectral analysis method¹ is then used to calculate both transition intensities and frequencies for coupled electron-nucleon quantum mechanical transitions. This approach is particularly useful in treating perturbations on the coupled spectra. We have reported² cases of strong coupling and chaotic motion in a simple model having extreme ionizations. We report here on dynamics of this model system in the presence of an intense laser field.
