Abstract
Sound velocity of laser-irradiated iron foils was
measured with side-on x-ray radiograph technique. Iron foils were irradiated
with two-stepped laser pulse to reach earth's core condition. We measured
not only the sound velocity but also temperature, pressure, shock velocity,
compressibility, and particle velocity. The experimental parameters of
temperature and pressure were very close to the earth's core condition. The
experimental results on the sound velocity are in good agreements with
previous experimental results and one-dimensional simulation results.
