Abstract

es the experimental shadowgrams (e.g. the radio-continuum and [OIII] images of the SNR DEM L316, Murphy-Williams et al. 1997) The yguazu-a code was also employed for studying the SNR 3C400.2. This SNR has a morphology of two apparent shells, partially overlapped in the direction to the NW, as revealed by the radio-continuum study carried out by Dubner et al. Instituto de Ciencias Nucleares, UNAM, Apdo. Postal 70-543, 04510, Mexico D.F. Centro de Instrumentos, UNAM, Apdo. Postal 70-186, 04510, Mexico D.F. Instituto de Astronoma, UNAM, Apdo. Postal 70-264, 04510 4 Facultad de Ciencias, UNAM, Mexico (1994). Di#erent models can be considered in order to explain this double shell structure, such as the interaction between two SNRs or the evolution of a single SN explosion occurring in a stratified medium. A preliminary H# analysis (de la Fuente & Rosado 2002) and the HI study carried out by Giacani et al. (1998) support the last scenario. Then, in our simulation we consider
