Quantum Control of Nuclei with Coherent x-ray light Adriana Palffy
Nuclear excitations and the XFEL XFEL bridge the gap between nuclear excitation and photon energies... Doppler shift 223Ra 50.1 keV 3/2+ 0 keV 3/2- T. Bürvenich, J. Evers and C. H. Keitel, PRL 96, 142501 (2006)
What about the Petawatt laser? PW laser • Create the dense plasma for NEEC/NEET? NEEC: to compare advantages of a dedicated electron target! • Help have an ion accelerator and XFEL at the same spot? • Will ELI provide ion acceleration • and coherent x-rays or gamma-rays? • If yes, good enough for nuclear applications? • NIF? Plenty of electrons, photons, neutrons. Can we model/analyze what is going on?
Conclusions • Driving of nuclear transitions via electrons or photons • Nuclear quantum optics applications for XFEL light Coherent control of nuclei in a three-level system NEEC NEET triggering level isomer ground state STIRAP with nuclei Isomer depletion – nuclear batteries? • Combination of nuclear excitations in plasmas: trade-off between • control and efficiency?
The theory is now sufficiently well understood that competing nuclear excitation by scattered electrons and direct photons can easily be calculated leaving NEET/NEEC experimental comparisons with theory meaningful
Sylvia talked about about electron acceleration up to about GeV in Wakefield acceleration and when coupled to either undulators or Betatron Emission mode promised monochromatic photons up to MeV levels

GRLS) Gamma ray resonant fluorescence Mainland security Nuclear waste reclassification
Storing radioactive waste at power stations There are hundreds of thousands of such barrels world wide with very little knowledge of the contents. GRLSs would enable certifiable classification of the waste contents
Depository of hundreds of drums of radioactive waste
Antimatter creation (Positrons) using Intense lasers Via Bethe Heitler Process Z+e- =Z+2e- + e+ Trident Process Z+γ = Z+e- + e + Using different thicknesses of targets
Although laser created positrons have been seen before Chris indicated that programs on VULCAN and Gemini had not been successful. However what had been learned could eventually lead to successful results in the future with the counter-propogating beams in vacuum leading to creation of antimatter
