The pressure-volume relationship in YbTe has been studied by high-pressure x-ray diffraction up to 300Kbar.This relationship is anomalous in the region 150-190Kbar indicating a continuous electronic collapse with pressure, in which the Yb2+changes to Yb34 state.This must involve 4f-5d electron promotion and result in a semiconductor-to-metal transition.The behavior of suggests that to rare-earth chalcogenides with large band gap a continuous transition would be favored
