Abstract

Kinetic energy distributions of Ni atoms in six electronic fine structure states ejected from a single crystal Ni{001} surface due to bombardment with 5 keV ${Ar}^{+}$ ions have been measured. These states arise from two different electronic configurations, $3 d^{8} 4 s^{2} {a {}^{3}F_{4, 3, 2}}$ and $3 d^{9} 4 s^{1} {a {}^{3}D_{3, 2} or a {}^{1}D_{2}}$ , which form three distinct fine structure manifolds within 0.422 eV of the ${}^{3}F_{4}$ ground state. We find that the band structure effects dominate leading to larger populations in the excited ${}^{3}D_{3, 2}$ states than found for the ground state.
