摘要：

Analysis of a CCD image of the remnant of Tycho's supernova made in the forbidden coronal green line fails to reveal emission at a limit of 3.1 × 10-8 ergs cm-2 s-1 sr-1 on the location of the reverse shock into the ejecta. The nondetection may imply (1) that the reverse shock has not yet reached Fe-enriched ejecta or (2) that the known dumpiness of the ejecta prevents production of observable amounts of Fe+13.
