    "abstract": "We present the first application of statistical spectroscopy to study the\nroot-mean-square value of the parity nonconserving (PNC) interaction matrix\nelement M determined experimentally by scattering longitudinally polarized\nneutrons from compound nuclei. Our effective PNC interaction consists of a\nstandard two-body meson-exchange piece and a doorway term to account for\nspin-flip excitations. Strength functions are calculated using realistic\nsingle-particle energies and a residual strong interaction adjusted to fit the\nexperimental density of states for the targets, ^{238} U for A\\sim 230 and\n^{104,105,106,108} Pd for A\\sim 100. Using the standard Desplanques, Donoghue,\nand Holstein estimates of the weak PNC meson-nucleon coupling constants, we\nfind that M is about a factor of 3 smaller than the experimental value for\n^{238} U and about a factor of 1.7 smaller for Pd. The significance of this\nresult for refining the empirical determination of the weak coupling constants\nis discussed.",
