The around-the-mean-field version of the LDA+U method is
applied to investigate electron correlation effects in
δ-. It yields a non-magnetic ground state of
δ-, and provides a good agreement with
experimental equilibrium volume, bulk modulus and explains
important features of the photoelectron spectra.
