Abstract

Relativistic configuration interaction calculations show Hf has only one bound state, 5d26s26p J = 5/2. The electron affinity is determined to be 0.114 eV. Using a fixed photon energy of 2.34 eV (∼532 nm), the partial cross sections to energetically accessible neutral states are calculated. It is found that the 6p detachment into the Hf I ground state 5d26s2 3F2 dominates the photoelectron spectrum. The effect of resonances is included using Mies's formalism.
