    "abstract": "Based upon the Bonn meson-exchange model for the nucleon-nucleon ($NN$)\ninteraction, we study systematically the charge-symmetry-breaking (CSB) of the\n$NN$ interaction due to nucleon mass splitting. Particular attention is payed\nto CSB generated by the $2\\pi$-exchange contribution to the $NN$ interaction,\n$\\pi\\rho$ diagrams, and other multi-meson-exchanges. We calculate the CSB\ndifferences in the $^1S_0$ effective range parameters as well as phase shift\ndifferences in $S$, $P$ and higher partial waves up to 300 MeV lab. energy. We\nfind a total CSB difference in the singlet scattering length of 1.6 fm which\nexplains the empirical value accurately. The corresponding CSB phase-shift\ndifferences are appreciable at low energy in the $^1S_0$ state. In the other\npartial waves, the CSB splitting of the phase shifts is small and increases\nwith energy, with typical values in the order of 0.1 deg at 300 MeV in $P$ and\n$D$ waves.",
