Abstract

We have proposed an advanced technique to measure the ^93mNb yield precisely by Resonance Ionization Mass Spectrometry, instead of conventional characteristic X-ray spectroscopy. ^93mNb-selective resonance ionization is achievable by distinguishing the hyperfine splitting of the atomic energy levels between ⁹³Nb and ^93mNb at high resolution. In advance of ^93mNb detection, we could successfully demonstrate high resolution resonant ionization spectroscopy of stable ⁹³Nb using an all solid-state, narrow-band and tunable Ti:Sapphire laser system operated at 1 kHz repetition rate.
