In this letter, we present an experimental study of shock propagation in a decreasing density gradient which is a common feature in many astrophysical objects. An original scheme for the targets has been designed to investigate the case of a discrete density step. Using foams in a wide density range (20-400 mg/cm-3), we obtained accurate data on shock acceleration at the solid-foam interface. Results are discussed and compared with models.
