G. Golovin, D. Uryupina, R.Volkov, and A. Savel’ev Registration of 14.4 keV 57Fe nuclear state excitation induced with the help of plasma created by the powerful femtosecondlaser pulse Faculty of Physics and International Laser Center of Lomonosov Moscow State University Moscow, Russia
The main question: Is a table-top instrument for nuclear physics real?
1 0 Femtosecond laser-induced plasma target electrons ions radiation
Main features of plasma-based nuclear instrument • Simple • Low-cost • 3-in-1: electrons, ions, and radiation • Direct excitation of low-laying nuclear levels
Task formulation Excite nuclei with the help of plasma, created by the powerful fs-laser impulse, and detect its deexcitation.
Deexcitation mechanism 57Fe Nucleus Atom 0 7,2 keV 14,4 keV 1
Results Signal from MKP Electron current (W=const) Fe2+ e,γ p Fe3+ Fe1+ plasma creation target Fe target 57Fe
Discussion 57Fe Atom Nucleus 0,8 keV 7,2 keV 14,4 keV
Conclusions Conversional deexcitation of 14.4 keV 57Fe nuclear state excited with the help of plasma created by the powerful femtosecond laser pulse was detected. Thank you for attention
