    "abstract": "Expressions for the P,T-violating NN potentials are derived for $\\pi$, $\\rho$\nand $\\omega$ exchange. The nuclear matrix elements for $\\rho$ and $\\omega$\nexchange are shown to be greatly suppressed, so that, under the assumption of\ncomparable coupling constants, $\\pi$ exchange would dominate by two orders of\nmagnitude. The ratio of P,T-violating to P-violating matrix elements is found\nto remain approximately constant across the nuclear mass table, thus\nestablishing the proportionality between time-reversal-violation and\nparity-violation matrix elements. The calculated values of this ratio suggest a\nneed to obtain an accuracy of order $ 5 \\times 10^{-4}$ for the ratio of the\nPT-violating to P-violating asymmetries in neutron transmission experiments in\norder to improve on the present limits on the isovector pion coupling constant.",
