  1. FINAL REPORT ON THE TOPIC 06-4-1036-2001/2004 “Nuclear Physics with Neutrons – Fundamental and Applied Investigations” Topic leaders: W.I. Furman V.N. Shvetsov

  2. Main Directions Total number of published works around 300 130 of them are at reviewed magazines • Experimental and methodical developments planned for high resolution neutron sources (IREN , nTOF, ORELA, KENS) • Research focused on high flux neutron sources (IBR-2, HFR/ILL, JAGUAR, PSI, PIK) • Applied Research • Analytical Investigations at the IBR-2 Reactor, Project REGATA

  3. Scientific Highlights of 2001 – 2004 KaTRIn project Development of Neutron Polarizer-Analyzer System for T-Invariance Experiment V.R. SkoyA1, Y. MasudaA2, S. MutoA3, T. InoA3, G.N. KimA4 A1 Frank Laboratory of Neutron Physics, JINR A2 IPNS, Tsukuba, Ibaraki, 305-0801, Japan A3 IMSS Tsukuba, Ibaraki, 305-0801, Japan A4 IHEP, Kyungpook National University, Korea

  4. KaTRIn project

  5. KaTRIn project PHE = 63% PHE = 54% Neutron polarization with quartz cell Neutron polarization with sapphire cell

  6. KaTRIn project Nuclear target polarization. First key methodical result have been obtained recently in collaboration with KENS group: Xe gaseous target at low pressure was polarized successfully at several percent level. Next step should be increasing Xe pressure and degree of polarization at acceptable level of relaxation time This work is planned for nearest 1,5 years

  10. Parity Violation Effect – Neutron Spin Rotation and Its Reason 1 – Isotope under investigation (with p-resonance) 2 – Reference isotope (without p-resonance)

  11. Interference effects in the resonance - neutron induced fission of 239Pu

  12. Activity at n_TOF CERN

  13. JINR – IPE – CERN Collaboration Results of 2003: fine structure of the vibrational fission resonances. Fund. Nucl. Phys. Activity at n_TOF CERN

  14. JINR – IPE – CERN Collaboration Results of 2003: fission x-session of 232Th, 233-238U, 237Np, 241-243Am and 245Cm for the Thorium cycle and MA incineration in ADS systems. Appl. Nucl. Phys. Activity at n_TOF CERN All experiments at n_TOF are conducted with total financial support of CERN

  15. Scientific Highlights of 2001 – 2004 UCN physics and neutron optics • UCN weak upscattering • Neutron interaction time • Time focusing Direct n-n scattering length measurements

  16. Applied studies HEND has 4 signals of neutrons from sensors SD, MD, LD and SC/IN, and for each of them the map of orbital measurements is currently produced. The map of MD sensor is contributed by epithermal neutrons mainly left (top). This MD map is consistent with the map for epithermal neutrons from Neutron Spectrometer (bottom) Count rate over the South Pole is 5-10 times lower (blue region) – doubtless water presence

  17. Analytical Investigations at the IBR-2 Reactor Project REGATA

  18. Priorities for the Future Scientific Program • Fundamental Physics: • Symmetries breaking in neutron induced reactions (KaTRIn & POLYANA projects, n-n scattering) • Fundamental properties of the neutron (neutron polarizability, n-e interaction) • Study of Polarized, Aligned and Unpolarized Fissioning Nuclei Using Polarized and Unpolarized Neutrons • Astrophysical aspects of neutron physics • UCN physics and quantum optics

  19. Priorities for the Future Scientific Program • Applied Physics: • REGATA project • Planetary science with neutrons • COmbined COrrelative Spectroscopy for materials studies
