    "abstract": "A low-energy shape-independent expansion is suggested for the function\n$[tan(2\\epsilon_{BB})/(2k^2)]$, where $\\epsilon_{BB}$ is the Blatt-Biedenharn\nmixing parameter for the $^3S_1 -$ $^3D_1$ channel. This expansion allows an\nevaluation of the mixing parameter $\\epsilon_{BB}$ from a knowledge of the\ndeuteron asymptotic $D$ to $S$ ratio, pion mass and other low-energy\nobservables, such as the scattering lengths, deuteron binding etc., of the\nnucleon-nucleon system. We demonstrate that the correct long range behavior of\nthe tensor potential is essential for a realistic reproduction of\n$\\epsilon_{BB}$.",
