  Title: OBSERVATION OF VELA SNR SHRAPNEL D                                              


Abstract:
 There are several cusps structure outside the Vela SNR. They are strongly considered
 as shrapnels launched in the SN explosion. We observed one of them and found that it
 is heavily overabundant of Si. This supports the idea that it surely comes from the
 ejecta of the SN. We propose to observe another cusp strucutre that is brighter and
 bigger than that we observed so far. Based on the Rosat result, we can expect much
 more overabundant of heavy elements.
