Abstract
The displacive transition in La is studied in the pressure range up to 26 GPa and under temperatures up to 630 K with angular dispersive X-r ay diffraction at the ESRF and with energy dispersive X-ray diffractio n in HASYLAB to elucidate further details of this transition with an e xtension of the transition line up to 22.5(5)GPa and 590(10) K and a d etermination of the order parameter down to a level of eta approximate to 5.10(-4).
