Dipole-forbidden transitions of nuclei interacting with super-intense laser fields — •Adriana Pálffy1, Thomas J. Bürvenich2, Jörg Evers1, and Christoph H. Keitel1 — 1Max-Planck-Institut für Kernphysik, Heidelberg — 2Frankfurt Institute for Advanced Studies
With present and upcoming light sources, the direct interaction between nuclei and super-intense laser fields has become feasible, opening the new field of nuclear quantum optics [1]. While for atomic systems the dipole transition is playing the most important role [2], in the case of nuclei, which present rich structural properties like collective and single-particle excitations, mostly dipole-forbidden transitions occur. The spectrum of E1 transitions is limited to few low-lying nuclear excited states with small reduced transition probabilities, and giant resonances, at energies of several MeV, which are not directly accessible nowadays with the laser. We investigate dipole-forbidden transitions of nuclei interacting with super-intense laser fields, considering several stable nuclei with suitable first excited states. The strong reduced transition probabilities and the suitable energy values make E2 and M1 nuclear transitions good candidates for the resonant interaction between nuclei and laser fields. As an ultimate goal, one may hope that direct laser-nucleus interactions could become a versatile tool to enhance preparation, control and detection in nuclear physics.
