Extended energy loss fine structure (EELFS) above the M2,3-edge of amorphous Ge was measured and evaluated in the previously developed calculational scheme taking into account the 3p- and 3d-ionization channels. The 3d-ionization contribution is prevalent in the EELFS spectrum of Ge in contrast with the case of EELFS for 3d-transition metals. The influence of both plasmon excitations and 3p-spin-orbit splitting on EELFS was considered. The excellent agreement of the experimental and theoretical results confirms the possibility of the nearest neighbour distance determination with high accuracy by shallow level EELFS technique.
