The propagation rates of longitudinal and transverse waves in polycrystalline lithium have been measured by a pulsed ultrasonic method at T = 78 K under pressures up to 1.6 GPa. The equation of state and elastic properties of lithium as a function of the pressure have been determined. It has been postulated that the sharp softening ({approx}14%) of the shear modulus G(p) of lithium in response to the first application of pressure at 78 K is caused by accumulation of the low-temperature martensitic phase. 29 refs., 3 figs.
