  1. + + + + + + + + + Nuclear Coherent Population Transfer with X-Ray Laser Pulses~One Step towards Nuclear Quantum Optics Wen-Te Liao Supervised by Dr. Adriana Pálffy Prof. Dr. Christoph H. Keitel • Max Planck Institute for Nuclear Physics, Germany 11. 03. 2011. @ Bucharest-Magurele

  2. Motivation-Control the nuclear state triggering level isomer triggering 656.90 keV Stokes pump 324.47 keV isomer state 96.57 keV Nuclear Coherent Population Transfer (NCPT)

  3. Motivation-Nuclear Battery Stokes pump isomer state Store very large quantities of energy ground state K. W. D. Ledingham, P. McKenna, and R. P. Singhal, Science 300, 1107 (2003)

  4. Drive MeV transition with 10keV photon > MeV Photon energy ~10 keV • Blue shift ~100 keV ~10 keV γ 0 Nuclear states XFEL • Accelerated • Nuclei !! T. Tajima, Report on the ELI Science, p.14 (2009). T. J. Bürvenich, J. Evers and C. H. Keitel, PRL 96, 142501 (2006).

  5. Ion accelerator and XFEL areNOT put together now

  6. ELI will put compact ion-accelerators and Table-Top-XFELs together M. Fuchs et al., Nature Phys. 5, 826 (2009). compact ion-accelerator M. Dunne, Science 312, 374 (2006) NCPT T T-XFEL

  7. STIRAP stimulated Raman adiabatic passage (STIRAP) delay Stokes Pump • K. Bergmann, H. Theuer and B. W. Shore, RMP. 70, 1003 (1998).

  8. XFEL Temporal coherence is low. Coherence time ~ 0.2 fs The Technical Design Report of the European XFEL

  9. Seeded XFEL (SXFEL) transversely and temporarily coherent E. L. Saldin et al., Nucl. Instrum. Meth. A 475, 357 (2001).

  10. XFEL Oscillator (X-FELO) Diamond Diamond Reflectivity ~ 100% transversely and temporarily coherent K.-J. Kim, Y. Shvyd’ko and S. Reiche, PRL 100, 244802 (2008). Y. V. Shvyd’ko et al., Nature Phys. 6, 196 (2010)

  11. Two Schemes P Cross One Color Scheme Central frequency of P and S are the same. γ Nuclear beam S Parallel Two Color Scheme Central frequency of P and S are different. S P γ Nuclear beam W.-T. Liao, A. Pálffy, C. H. Keitel, arXiv:1011.4423v1.

  12. Results for One-Color Scheme 5 < γ < 36 Fully coherent XFEL: Photon energy = 25 keV Bandwidth = 2 meV W.-T. Liao, A. Pálffy, C. H. Keitel, arXiv:1011.4423v1. Increased

  13. Conclusion 1. NCPT can be observed with laser peak intensity > . ELI-NP provide very unique stage for NCPT. 2. W.-T. Liao, A. Pálffy, C. H. Keitel, arXiv:1011.4423v1.
