Abstract

Atomic electron binding energies for

{}_{100}{Fm}

have been measured (± ∼10 eV) for shells

K

L_{1 - 3}

N_{1 - 5}

N_{6, 7}

O_{1 - 3}

O_{4, 5}

, and

P_{2, 3}

from conversion electron spectroscopy in the

β

decay

{}^{254 m}{Es} \to {}^{254}{Fm}

. The

P_{2, 3}

value of 24 ± 9 eV is unexpectedly low compared to empirical and to self-consistent field-based extrapolations. Preferential judgements among published actinide binding-energy tabulations are presented.
