B. Simard et al., 1ST IONIZATION-POTENTIAL OF TANTALUM BY MASS-SELECTED DOUBLE-RESONANCE FIELD-IONIZATION SPECTROSCOPY, Physical review. A, 50(1), 1994, pp. 846-849
The first ionization potential of tantalum has been determined to be 6
0 891.4+/-0.2 cm-1 by performing double-resonance field-ionization spe
ctroscopy on a supersonic beam of laser-vaporized tantalum atoms.
