Abstract

Several two- and three-step schemes for resonance ionization of ⁹³Nb with field ionization of Rydberg levels were investigated in the context of feasibility studies of using ^{93 m}Nb/⁹³Nb isomer ratio determination for fast neutron dosimetry. Hyperfine structures of the states 4 d⁴(a⁵D)5 p⁴D₁^2/0, 4 d³5_s(a⁵P)5 P⁶D₁^2/0, 4 d³5 s(a⁵F)5 p⁶F₁^2/0, and 4 d³5 s(a⁵F)6 s⁶F_1/2 of ⁹³Nb were measured. The Rydberg spectra of the excitation schemes were measured and corresponding ionization limits estimated.
