The excavation mass M(sub ex) is shown to be nearly M(sub ex) proportional to nu (nu is projectile's impact velocity), while, it depends on the projectile mass m as followed: M(sub ex)/nu proportional to m(sup 0.6 to 0.8). The present results also show that the excavation mass depends on the target grain sizes., 資料番号: AA0047898004}, pages = {13--16}, publisher = {宇宙航空研究開発機構宇宙科学研究本部, Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA/ISAS)}, title = {Measurements of the amount of excavated material in impact cratering}, year = {2004} }
