Anomalies in elastic properties and features of electronic transitions in lanthanum and praseodymium at pressures up to 84 kbar

The propagation velocities of longitudinal and transverse elastic waves in polycrystalline praseodymium have been measured by a pulsed ultrasound method at pressures up to 84 kbar at room temperature. The density, elastic constants, and Debye temperature are calculated as functions of pressure. The...
