    "abstract": "The nuclear physics dependence of the exotic $(\\mu^-,e^-)$ conversion\nbranching ratio $R_{\\mu e^-}$ for the experimentally most interesting nuclei\n$^{208}Pb$ and $^{48}Ti$, is investigated in various nuclear models. The\nresults thus obtained are combined with the new experimental limits extracted\nat PSI for these nuclei to put bounds on the elementary particle parameters\nentering $R_{\\mu e^-}$ such as intermediate neutrino masses and mixing angles\nas well as relevant parameters of intermediate supersymmetric particles (masses\nand mixing of s-fermions and neutralinos).",
