摘要：
We have developed a novel method to measure sound velocity of laser-irradiated iron foils by side-on x-ray radiograph technique. Iron foils were irradiated with two-stepped laser pulse to reach the earth's core condition. We obtained not only the sound velocity but also temperature, pressure, shock velocity, compressibility, and particle velocity of the laser-irradiated iron. The experimental results are in good agreements with previous experimental results and with one-dimensional simulation results.
