Subject: SUPERNOVA REMNANTS AND GALACTIC DIFFUSE EMISSION            
  Title: SEARCH FOR THE YOUNGEST GALACTIC SUPERNOVA REMNANT                              


Abstract:
 44Ti is the radio isotope which is synthesised with supernova explosions. Since its
 half-life is very short --- about 48 yr ---, it has been regarded as a good
 indicator of young supernova remnants (SNR). In 1994, 44Ti gamma-ray emission line
 (1.157 MeV) was actually detected from Cas A using COMPTEL. From not only Cas A but
 also another region, 77Ti emission has been detected. We propose the ASCA pointing
 observation of the region in search for the youngest unidentified Galactic SNR. This
 observation aimes to establish the method of the very young SNR search and to make
 clear its physics. We think this is the good case of the international collaboration
 using COMPTEL, ROSAT, Einstein, Ginga and ASCA data. At the same time, we place it as the pilot observation of ASTRO-E.
