To verify the first-order liquid-liquid transition (LLT) in liquid Cs reported by Falconi , the pressure dependence of liquid density was measured up to 5 GPa by an X-ray absorption method. The results showed that the density continuously increases over the entire pressure region investigated, without showing the previously reported large volume jump (/ -17%) at 3.9 GPa. No existence of the volume jump is also suggested from the slopes of the melting curve in the phase diagram. Although the electronic transition is one of the most promising candidates that may cause LLT, it is unlikely to occur in liquid Cs because of the gradual nature of the 6-5 electron transfer.
