抄録（英）
We carry out the impact experiments at velocities higher than ca. 10 km/s and observe x ray radiated from the impact-induced vapor clouds. The x-ray energies are in the order of 10((exp -3) times projectile kinetic energy. Based on the experimental results, we evaluate the feasibility of the observations of Late-Heavy-Bombardments (LHB) on extrasolar planets at 10 pc from Earth and of impacts at the Moon surface. The detection of the x ray caused by LHB on extrasolar planets seems difficult, but the size distribution of minor-solar system bodies with a size larger than ca. 1 cm may be evaluated by the x-ray observations of the Moon surface.
