摘要: Recent work on the sizes of craters produced by ion impacts solids has shown that size crater scales with inverse square cohesive energy. This observation is in contrast to macroscopic impacts, which scale directly It relied assumption melting temperature proportional Using computer simulations, we now show fact product and provides direct proof reason different behavior ion-induced cratering flow liquid ions.
