      abstract     = {The partial phonon densities of states of iron atoms in the
                      intermetallic compound FeSi have been measured in the
                      temperature range 46–297 K using nuclear resonant
                      inelastic scattering of synchrotron radiation. A significant
                      phonon softening with increasing temperature has been
                      established. The greatest phonon softening for iron atoms is
                      shown to occur in the region of long-wavelength acoustic
                      phonons, for the acoustic branches near the boundary of the
                      Brillouin zone, and for the low-lying weakly dispersive
                      optical branches. The results obtained are analyzed in terms
                      of the views that relate the change in the phonon density of
                      states of iron atoms to the temperature evolution of the
                      electronic density of state for the compound.},
