Popis:	In the context of exploring mass distributions of dark matter haloes in giant ellipticals, we extend the analysis carried out Merrifield and Kuijken (1998) for stellar line profiles of shells created in nearly radial mergers of galaxies. We show that line-of-sight velocity distributions are more complex than previously predicted. We simulate shell formation and analyze the detectability of spectroscopic signatures of shells after convolution with spectral PSFs. Comment: 4 pages, 3 figures, to appear in the Proceedings of the Galaxy Wars: Stellar populations and Star Formation in Interacting Galaxies Conference, minor corrections in caption of Fig. 2
