Subject: SUPERNOVA REMNANTS AND GALACTIC DIFFUSE EMISSION            
  Title: MSH 11-62: ASCA STUDY OF A CRAB-LIKE SUPERNOVA REMNANT                          


Abstract:
 We propose an ASCA observation of the Crab-like supernova remnant MSH 11-62. MSH
 11-62 shows distinct evidence of a central engine powering a synchrotron nebula. The
 radio spectrum is relatively flat, the X-ray spectrum appears to be nonthermal and
 an EGRET source has been associated with the SNR. The proposed ASCA observation will
 fully characterize the nature of the emission and identify the contribution from a central pulsar-driven synchrotron nebula.
