Abstract
X-ray diffraction data recorded with a four-circle diffractometer prov
e that BaLiF3 is one of the rare example of inverted perovskite. The l
ow frequency phonon spectrum is investigated by inelastic neutron scat
tering and the whole spectrum is calculated using a rigid ion model. A
n estimation of the phonon density of states is deduced.
