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