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 mNb/93Nb isomer ratio determination for fast neutron dosimetry. Hyperfine structures of the states 4 d4(a5D)5 p4D12/0, 4 d35s(a5P)5 P6D12/0, 4 d35 s(a5F)5 p6F12/0, and 4 d35 s(a5F)6 s6F1/2 of 93Nb were measured. The Rydberg spectra of the excitation schemes were measured and corresponding ionization limits estimated.
